    Perfect fit
    These Filtrete air filters are excellent. The build quality is solid, and the frame holds its shape perfectly during installation — no bending or collapsing like cheaper ones. The MERV 11 rating makes a big difference in capturing dust, pollen, and pet dander; I can definitely tell the air feels cleaner, and there’s less dust settling around the vents.They fit snugly in my HVAC system, and airflow remains strong — no drop in performance. I change mine every 2–3 months, and the used filter always shows how much it’s caught, which proves it’s doing its job.Pro tip: write the install date on the edge with a marker — makes it easy to track replacement cycles.If you have allergies or pets, these are absolutely worth the upgrade from basic filters. Reliable, effective, and great value for the air quality improvement.

    Great Quality Filter with Perfect Fit
    This 20x20x1 AC filter exceeded my expectations.Installation was extremely easy, and it fit perfectly into the AC slot without bending or having to force it. The filter feels solid and has a good level of density, which helps capture fine dust, pet hair, and other particles from the air. After installing it, I noticed better airflow and the air in the house feels much fresher.For the price, this is an excellent option to keep your AC running efficiently and your home cleaner.

    Great product! Buyer since over 5+years ! Definitely worth it
    I’ve been using these for more than five years for my furnace. Never no issues. Delivery is great. I’ve only had maybe two times over the course of five years that the package came in damaged, but Amazon was great to replace the items immediately and these filters are quite amazing and the value was good for a 2 pack !! Highly recommend and keeps your furnace, clean and running properly!!

    Great Filter – Does Exactly What It Should
    These Filtrete filters work perfectly for my AC unit. The fit is spot-on for my 16x20x1 system, and I’ve noticed they do a great job keeping the air clean. They’re easy to install and seem to catch a lot of dust and allergens. For the price, you really can’t beat the quality. Highly recommend if you need a reliable filter that actually does its job well!

    Wrong Size
    I live in an apartment that supplies free air filters each month. With that privilege, they provide the worst possible air filters you can imagine that provide no type of protection, whether that’s a HEPA filter, virus protection, dander, etc., whatever you are looking for, apartments will give you the most affordable filters for their budget and don’t care about human protection and safety. So, I like to purchase my own filters but they are super pricey going this route. Quality vs. Quantity.My apartment filter is measured at 20x20x1 which is what I ordered on Amazon (the Merv 11). It absolutely does not fit my air conditioner. Now, when I purchased a 20x20x1, same brand, at Walmart, it did fit – but online I somehow got a different size. It was too tall/large for my unit and I had to cut the top portion off just so I could get my monies worth.I will say that it does a great job at collecting dust; even found a moth sucked into the unit the other day; but I don’t think it really helps as far as smells go. I have a partner that smokes cigs and does not understand what air pressure means when he tries to stand at the back door and blow the smoke outside, opposed to his full body being outside and the door is closed. Due to the air pressure, the smoke just comes right back inside. I do have 3 name-brand purifiers around my house doing most of the legwork, but they can only do so much. The filter doesn’t filter smoke.It also states it’s a 3-month filter – I don’t know how to calculate that. I think it maybe can hold “gunk” up to two months depending on your home, the amount of dust and pet dander you have, and other factors that play into it – but from a mental standpoint, I would not be able to leave a filter full of pet dander and dust in my unit for 3 months. My apartment collects a ton of dust and pet dander so 2 months max. I will say it is pretty good quality material compared to my standard apartment’s filter where you can see through it and there’s no visible protection. This filter actually has a thick layer of protection – so for the brand, and honestly being able to get more than one month’s use out of it, I will absolutely return, but we need to get our measurements figured out.

    Great filter. After speaking with the HVAC specialist that services my system I feel comfortable using the 1000 as it balances air flow and cleanliness.Pros-collects dust and hair-lasts anywhere between 2-3 months-arrow clearly indicates which air flow direction to place the filter

    Facil de cambiar sin problemas de los que se lavan y hay que esperar a que sequen para volver a colocar.
