Nice filter

So far, so good. The duct cleaning guy who installed it for me was very complimentary of it.

I’m considering ordering a second one. I’m going to save a ton on filters with this one.

just changed over and have not had enough time to form a opinion.

Perfect Fit

The HVAC service guy liked the new custom fit filter saying, “It fits like a glove”.

Great replacement filter

Great replacement filter for my furnace, custom made for my needs, high quality, a muat have !!


Good…but no instruction?

The filter is perfectly sized…it was a custom order. But…either I can’t find…or they forget to put on a sticker….I’m not sure which side is up. ??? And I’m not finding that info. on the website. A small quibble.

Works Well So Far!

Got the filter in and it was a perfect fit for our unit. After installation, there was a slight whistling noise when the A/C would come on, but that was easily remedied with a small wash cloth between the filter and housing. I'm happy with our purchase.

Quality work, fits right in

The new filters have improved the air in my house. They fit perfectly!

MaxMERV9 Filter

I received my MaxMERV9 Filter on 03-23-2024. The filter was damaged and I contacted Scott in sales. Scott said they would send out a replacement. I received the replacement filter on 04-02-2024. The replacement filter was also damaged much more than the first. I sent a e-mail to Scott with photos on 04-02-2024 and have not heard back. I have not been able to use the filter yet so I can not provide an review. I expect to hear from Scott soon. He has been very good at responding to my e-mails. It appears that the problem is with the shipping company.

No you haven’t I’m still waiting. Sent my filter to a wrong address.

Order hasn’t been filled after substantial time

Works great just wash it shake the water out and stick back in

Excellent filter

We bought it online for our air conditioner. It was easy to install. We are happy with it.

Best experience ever!

Not only was my black custom sized filters perfectly manufactured, but they arrive day before they were scheduled. What more can you want from a company!

Platinum 1 inch

I am hoping that this filter will last as long as my prior one, which was not your product. I still have the old one that I've used for over 15 years. I will alternate these as they need cleaning/vacuuming. Appreciate finding your site.

Never Changing Filter Again!

I requested a custom size, partly based on which filter was currently in place (height & depth) and which filter size (width) the user manual advised. The new filter arrived quickly ... within 2 weeks??? It arrived in good condition! The filter was a perfect fit! My heating system can accomodate a filter that is about 4" wide so I was concerned that the 2" filter might not stay in place. While I had a 'plan B', it seems that maybe the weight of the new filter helps to keep it in place - no additional adjustments were needed. One concern was how the filter should be positioned relative to the direction of the air flow. I saw a paper attached to one filter edge - the paper advised of the direction. That paper can be easily damaged when I wash the filter, so I used a marker to arrow the air flow direction. The only negative regarding this purchase was the existence of the paper with the small writing! In my opinion, the air flow direction should be etched on one edge of the filter, or even hand marked (not realistic - labor costs?). At any rate, I look forward to cleaning the filter at reasonable intervals, and I look forward to the filter's long life!!

Good filter. Would definitely order from them again.

The accumulation of dust, my main concern, is now controllable, that is why I ordered a back-up filter.

So much less dust….

We live in the desert and this filter is the answer we have been looking for. Easy to clean and so far as filtered much more of the desert dust. The dust is red here so we can tell..
