DPF Cleaning in Phoenix, AZ

Dpf alternatives has helped me tremendously with my truck and they have been very friendly and responsive. I would highly Recommend using them versus dealerships or other mechanic shops!

Honest and great service, fixed the problem, for very reasonable price!

Very knowledgeable place , excellent service, fast and reliable, many parts in stock

They took good care of me- cleaning up my dpf and communicating well all along the way including after the work was completed. Highly recommend!

Thanks for getting me in to fix my truck. This is a great place to service. And big thanks to Leo.

i recently bought a w900 that was throwing engine codes and had a permanent dpf code that was throwing the truck into a derate and not running properly. After taking it to kenworth and almost dropping $6000 my truck was still having the same issues. After some research i found Leo with Dpf alternatives and immediately brought my truck to him. He is honest, reliable, and does work for a great price. He also offers some good feedback on how to properly manage your dpf system. I highly recommend.

Had a DOC reconditioned. Got it back quickly and it is flawless. Saved me a couple thousand dollars! Thanks Leo!!!

A++ service. No problems, a very fair price for dpf cleaning.

High quality work, professionalism, prompt service, fair prices and works on weekends in a pinch. THIS SHOP HAS IT ALL. Special thanks to Leo Reyes and crew for a DPF filter swap and regen in lest than 5 hours. Truly outstanding!!!

Searched around at a couple of places but had 2 good friends highly recommend DPF Alternatives. They were able to get me in pretty fast and the price for the service was very reasonable. Very happy with the service and communication. Don't waste your time going anywhere else! DPF Alternatives is a solid choice 👌 Thanks again !

Needed the exhaust filters burned. Got back some brand new lookin filters. Reasonable pricing, fast turn around, outstanding work.

Good service, clean my def filter and back on the road.

Guaoo best and best nice places in very good people and recommended all drivers 👍 👌

We've been using the Catalyst product consistently for 9 months and 90k miles on a 2017 Cascadia with a DD15. The truck has 638k miles on the original OneBox still has excellent pressure readings. I credit this to the Catalyst product, Delo XLE 400 and a well maintained Thermoking APU. I enjoy buying the Catalyst in Phoenix at DPF Alternatives. Very convenient and accessible for big trucks. Leo is great! Very accommodating and he's always eager to share his specialized and unique knowledge.

I took my truck from the dealer wanting to replace my exhaust. DPF ALTERNSTIVES fixed my exhaust replaced what needed to be replaced. Truck runs better. No constant regeneration notifications and increased mpg. I would recommend them to my friends if they needed that type of service.

Brought my truck in thinking I would be down for at-leased a week. Leo and his crew had my filters cleaned and I was back on the road with a little more than a 34 hr reset. Leo also recommend me to start using Pittsburgh power. It has made a huge difference in how my truck drives. These guys know there stuff. I will be using them for anything to do with the dpf system.

They were responsible, quick and efficient. Definitely will refer their services in a heartbeat.

Honestly I never write reviews for a business but this one got it right on the money. They took my filter for cleaning last minute, explained the process in very good detail. I was very pleased with the end result and service.

I got the run around from freightliner in Phoenix for my exhaust system so I found this place through another shop’s recommendation they got me fixed up right away 5 days faster then freightliner said they would. They also recommended I start using a fuel additive called max mileage and I love it I’m getting better fuel mileage and my engine is running a lot smoother. I’m glad I found this place and I will be a customer for life.

Fix and Clean up my DEF system , it’s like new now. Last time got same problem and dealer can’t fix it. Now I am very satisfied!!

good service.

I highly recommend DPF alternative, they did an excellent job of getting my DPF Service done in one day.

We were extremely pleased. No dashboard codes upon lea We will make this our go to place go to place.[

They do good job

Truck was at the dealership for 12 days and they could not solve the problem and kept charging me more money to keep diagnosing it. Called these guys they got me right in had truck back on the road in a day and a half and charges were within $100 of what he estimated. I highly recommend them and will definitely use them in the future.

Came in with the dreaded onebox diagnosis.. total cleaning service took days, and although it was a big price tag it was nothing compared to the dealer estimated $15,000 and 3 month wait on parts... I'm very happy with the service... keeping me rolling...

Extremely knowledgeable and helpful when it comes to diesel particulate filtering systems. I've used this company more than once and I am completely satisfied. I would highly recommend them to anybody who's having issues with their diesel particular filter.

Those guys are good.

(Translated by Google) I am very satisfied with Leo's attitude. He is very smart and efficient at work. My volvo 860 smoke exhaust repair was very successful under his maintenance. Like him👍👍👍👍👍👍👍 (Original) 非常满意Leo得态度，他非常聪明而且干活又利索。我得volvo 860在他的维护下排烟修复非常成功。为他点赞👍👍👍👍👍👍👍

Good info and help.

Got me in short notice. DOC face packing. Performed Complete 1Box service in on Friday had it back on Tuesday . And back trucking. Leo was very communicative and kept me in the loop throughout the process. A1 service.

I wanted to wait a few weeks before leaving a review. I have a 2016 freightliner cascadia that was throwing several codes and check engine lights everytime I was climbing a grade. I called and spoke with Leo about my problems and he was able to get me scheduled for service. I have not had a code or engine light come on since DPF alternatives serviced my 1 box and replaced 3 sensors. My truck seems to be running better. I would and have recommended DPF alternatives for any DPF issues...

My husband’s diesel truck was having issues with the DPF system. From the beginning, these guys were straightforward, honest and extremely knowledgeable regarding the issues with the truck. They kept us updated throughout the process and were reasonable on pricing, with no unexpected costs. After picking up the truck, we instantly noticed horsepower and fuel mileage gains. They definitely gained a lifetime customer after this experience!

Great service

My Freightliner Cascadia needed to have the filters cleaned. Brought it to Leo and he was very knowledgeable and helpful. Amazing service and great prices. Will reccomend this place to every Owner Operater.

So I took My truck to velocity and was told I needed to replace my def box @ a cost of 15k. So needless to say I declined the repairs and called Leo(@dpf) and explained what was going on and he told me to bring it to him to check out. So I go to get the truck from velocity and they give it back to me but it's in default 25% degrade, mind you when I dropped it off it wasn't in default. So I asked what the hell and they tell me the only way to clear the codes is to replace this box which cost 10k alone , So I take my truck in default mode to Leo and he found the issue and fix my truck, and he didn't replace this box that supposedly the only fix for my issues ,,go figure right? At any rate before you get screwed over by Velocity on DEF issues give Leo a call @dpf alternatives he'll take care of you 💯

Services, was on point and on time I'll be keeping this company for this services for sure very satisfied. Mr Leo is easy to work with communicates always. 👍💪 Top notch

The guys at DPF Alternative Phoenix took real good care of me. The emissions system on my 2015 Freightliner Cascadia was on the rail and in need of some tlc. Leo and his skilled technicians wasted no time diagnosing the issues and making the necessary repairs, getting me back on the road with time to spare. They were very professional and took time to answer all my questions of which I had many. I highly recommend them and will be returning in the future for an ERG cleaning. Thanks again . Lonnie

I highly recommend “DPF ALTERNATIVES” my truck had a issue related to SCR SYSTEM. Leo is so professional.he fixed it earlier than I expected.next day i was on the road and I didn’t faced any issue yet related to dpf.everything working good.THANK YOU

The dealership wanted to replace my dpf filter in my 2019 Ram 3500 for about $3000 and a 1 week turn around. I found DPF Alternatives and spoke with Leo who is very professional, he said he could open up my filter and have it cleaned and put back together in a day. I was skeptical but he made it happen! I know have over 30k miles since the repair and my truck emission system has been working flawlessly. Leo also recommended that I run the Max Mileage to help keep the filter from plugging up when idling. I have noticed about half of the DEF consumption compare to pre Max Mileage usage. My DPF restriction gauge now never shows any restriction. I am very pleased with Leo and his team I highly recommend DPF Alternatives in Phoenix to anyone who is having emission problems. Thank you Leo for your hard work and doing exactly what you say!

Awesome friendly people there quality of work is top notch. After they cleaned my DPF system I am now getting a solid 1.0 MPG better fuel economy 👍👍 I will definitely be using them in the future.

Been having DEF problems for a while was recommended to DPF Alternatives. Leo explained a few things that could be wrong and explained the worst case scenario to the best possible scenario! Even though mine was in-between he kept my informed! Would recommend to my fellow drivers if any of them have this problem!!

We had our truck break down in Parker, AZ on a Sunday. After having a roadside service look at it and finding out that it was a DPF issue, I was lucky to find Leo from DPF Alternatives. After explaining what the issue was, Leo was able to provide some insight on what was necessary to repair it and what it may cost. He was very knowledgeable and helpful, so I had our truck towed in on late Sunday. Throughout the process Leo addressed any questions we had, provided updates on the repair process, and had the truck ready by Tuesday evening. He even checked out another unrelated issue with the truck for us. This is probably one of the best experiences I’ve had with a repair shop! Thank you Leo and DPF Alternatives Phoenix. Nat S. BSN Trucking

I dropped my truck off on Monday late morning.We discussed the symptoms and concluded that the full service was what was best. Leo went over what all was included in the service and I approved it. I told them I would be back on Thursday to pick it up. When I arrived the truck was complete and ready to go. After previously spending thousands of $ on a new one box, I concluded this process along with the use of the Pittsburgh Power Max Mileage additive is the way to go. While I only have run it for about 1500 miles, it it quieter and seems to respond better. My truck has 1080000 miles on it. I would strongly suggest this route if you have after treatment issues. The staff was very professional in explaining every step. The truck was completed on time as promised. I would recommend this shop highly.

I'am so glad I found DPF Alternative Phoenix, down time was short and they did an excellent job of explaining, and cleaning everything. When needing cleaning again I will definitely go back to Leo and the Guys at DPF ALTERNATIVES PHOENIX Job well done!!!👍. WNC TRANSPORTERS LLC.

Bought Pittsburgh Power here 01/16. I have been using it for months now. Excellent product, works as advertised. Keeps me running for the long haul 👍🏽

If you’re having DPF issues come here first! This is the only shop I know that can clean or replace your filter. My 2012 Ram 2500 DPF plugged up while pulling my RV. Dealer did a forced registration and got me back on the road but I wasn’t sure if I needed a cleaning or replacement. I called a few shops and no one could give me advice other than replacement since they aren’t setup for cleaning. Talked with Leo and felt informed about the cleaning process and he could also get replacement parts if needed. It turned out my filter was cracked and sensors fused to the filter. Leo was able to get me refurbished parts and save me lots of money compared to dealer pricing. Just got back from a 2,500 mile road trip pulling my RV and had no DPF issues. I also purchased a gallon of MaxMileage. I think it’s working but will need more time to form a strong opinion. Thank you Leo!

I recommend anyone that needs service on there, dpf filters. Come to these guys. It’s a small business and with that means . They put in hard Dedication and the best work. I’ll see u soon on next service Leo u the best .

I’ve running the truck for a few weeks after the DPF filter cleaning, feels like a different engine no more crazy regens and my fuel mileage improved by almost mile per gallon that’s how bad it was, and using less DEF fluid. You are awesome thanks for taking care of my Truck.

Great place. Great people

My truck is running great after cleaning. I originally brought just my DPF, but Leo suggested I also pull my NAC. Both were cleaned in their ultrasonic process and the truck is running great. Communication along the way was excellent. I recommend DPF Alternatives in Phoenix. Great work and customer service. Correction, it was the NAC not the DOC. Mike M

This is the only place you should go to have your dpf cleaned. Leo is the best! Turned out my filter was trashed and needed to be replaced. I have a 2010 Cascadia and Leo found one in their franchise network and had it overnighted. A hell of a lot cheaper than the dealer! Excellent service and people. Leo is the man👍. I bought a gallon of Pittsburgh Power's max mileage fuel catalyst from Leo too. I highly recommend using that to help your engine produce less soot to keep your filters cleaner longer. Not to mention if your truck has def, it will use less def by using that product. Thank you again Leo for everything. A satisfied customer and future customer!👍

These guys rock. Came in early to help us out!

Amazing service was done for Scott Waste Services! Fast and efficient! Thank you for helping get our truck back on the road!

Leo did a great job. Cleaning the filter for us. After picking the truck up and driving about 60 miles we had a light come back on saying the filter needed to be cleaned again. I called Leo and he offered to have us bring it back. We discovered a whole in the turbo inlet cooler line causing the computer codes. I was able to fix the problem in just a few hours and the truck has been running great ever sense. I would definitely use these guys again.

It is wonderful place to take your truck went DPF filter need to be cleaned 24/7 service that’s event Better went working in Truking industry and last but not least great consumer service 👍 keep up the work

This is a place to get your DPF done at, they are quick and efficient, I was having problems they got me in and Out, very helpful and did not charge me an arm and a leg, I will go back again.. Thanks Leo

Leo, is a specialist. Cleaning and restoring after-treatment systems is what he does everyday. The proprietary cleaning process is more thorough and will give you more value for your time and money. I received prompt and reliable service to clean my DPF from a friendly team. Update: 6 months after my first visit for a filter cleaning: had a couple of codes pop-up (DPF differential pressure and turbo actuator) in Illinois and was heading to Phoenix. Pushed past a temporary 25% derate to try and make it back to Leo's shop. He went right to problems, changed the failed pressure sensor and replaced the actuator, all in one day, without the expensive wild-goose chase that you often get elsewhere. Great to have a skilled and honest technician to rely on. P.S. use the Max Mileage!! Multiple benefits including keeping your VGT vane within your turbo cleaner and moving freely. Typical actuator failure is due to a sticking VGT vane, which means both actuator and turbo must be replaced $5K +/- Ouch!

leo help me out with my dpf problem on my truck very honest about everything. And got the job done if I could give a 100 stars I would ! 😊

Definitely had a great experience with these guys,and definitely will return agin....Five star business..Thank you guys once agin from Charles Trucking inc

Anthony was the tech that helped me by trouble shooting my exhaust issues. He was very honest and did not take advantage of the situation. I highly recommend this company.

Had DPF and DOC cleaned in March. 3rd time it's been done. 1st time here. I can tell you that Leo knows what he's doing. It's by far the best Cleaning I've had done to my truck. I have gained somewhere between 1.5- 2.5 mpgs in the last month. If I could ever fix the NOX side of this truck I'd gain another 2mpgs again. If you dont live near here, get here. Bring a load in and let Leo and his Team do your truck right, the first time. It's far less expensive than getting repairs done by 3 different shops with three different opinions and diagnoses.

Wow! Just plain 'ole wow!! Called Sunday, arrived Monday, out Tuesday! And at a GR8 PRICE on my DPF baking. LEO and his brother ANTHONY are there to satisfy customers, and build their business. Im living proof... Even brought to a gr8 Motel, and came and got me the next day. Very pleased guys. Thx for being there..

These guy are are great, they will treat you with respect and try to help you in every way...

These guys were great to work with. Good to know there are still honest mechanics out there that dont just want to add on more unneeded repairs.

My whole experience was fantastic, which is amazing when you’re talking about truck repair places! Leo, the owner was easy to reach and got me in as soon as possible to clean my DPF filter. He had my truck ready when promised, and did an excellent job! That was about two months ago and everything is working perfectly. If you need to service your DPF, I wouldn’t go anywhere else!

Staff did a amazing job with my filter and catalyst. Dealership wanted over $3500 to fix and Leo at DPF Cleaning solution saved me $3000. Also, the turnaround on cleaning was fast, 1 day. Fantastic service, staff, and solution. Thank you.

I found leo and his brother on facebook in a group for cummins isx problems. They advertised that their ultrasonic cleaning system is far superior to the normal bake system that dealers use. When you walk in to their office they have several different dpf units cut in half showing the difference between the filter after they cleaned it and several from dealers after they said it was clean a few which show actual damage after the dealership said it was clean. Leo is very honest and trys to do the best job for the least amount that he can. I would recommend anyone to use dpf alternatives after my experience in phoenix. Thank you to leo and his brother for the great service

Can't say enough good about this place. Worked me right in and had me rolling again in record time. In the middle of the Christmas Holiday no less. Leo is the best!

(Translated by Google) Thanks a lot! (Original) muchas gracias!

I highly Recommend these guys here in phoenix and their advice for any DPF service hands down I called around and cheaper is not always better you get what you pay for but my truck is back up and running like normal and all at a fair price their advice saved me thousands and headaches down the road Thanks Again.

I give DPF a five star review. I was in a bind on a holiday weekend needing my DPF filters brought back to spec. With no questions asked Leo told me to bring my truck down on a Saturday and it would be done by Sunday at noon. My truck ran amazing when I got it. I couldn't be more happy. There was no downtime for my business. The best part is his price was far more affordable then others with a lifetime warranty. I am a customer for life and would refer him over and over. Support local small businesses. Thank you Leo for all your help!

Good guys! Did a good job on my truck. On time , professional and knowledgeable! I’m glad we have them in the area. SUPPORT LOCAL SMALL BUSINESS!!

I am so glad I found them they fixed my DPF and saved me a lot of money. Use these guys for DPF problems. Great Job!

2008 Dodge Sprinter. I was having issues with my DPF but the guys here totally helped me out. 230000 miles on my DPF and it has never been cleaned prior. After cleaning I did have to take it back to Mercedes to get the code removed and they said it was like if the DPF was brand new again. New ones retail for $1200 so I gave these guys a shot and glad I did. I was promised a t-shirt and never got it though :(

Very quick, professional and helpful. You definitely needs to hit this shop for DPF and Leo will get you out of there in 24 hrs .

Do you have any DPF problems??? You must go to here. They are the best.

Great customer service and did an excellent job on my dpf. They cut open the dpf because it was so full Of soot and when I installed it It lined up perfectly great job great customer service highly recommend
