Designed with exclusive Filtrete 3-in-1 technology, including a high MPR 1550 and MERV 12 rating, your AC filter will help pull and capture countless microparticles – such as pet dander, smoke and smog – while letting cleaner air flow through.

Your Filtrete Filter will also capture large particles, including lint, pollen and household dust. Use a 12-month 4-inch home HVAC filter in your compatible furnace, air conditioner or HVAC system. For optimal performance of your HVAC system, change your 4-inch furnace filter at least once per year. Fits systems calling for a filter thickness of 4.31"and larger. Filtrete™ Brand is North America’s most trusted brand of HVAC Filters (2). Residential use only. (1) % captured is based on ASHRAE 52.2 testing for 0.3 to 1 micron particles from the air passing through the filter, which relates to HVAC industry standard efficiency testing.

Fits the furnace perfectly and filters the air going through it. Not much else to say about it other than it does the job it's meant to do. Multi pack is nice and was packed well with no damage to the filters when they arrived. Unlike the national chain home improvement store where all of their filters look like they were run over by the fork lift.

Ships fast and arrives boxed in perfect condition. Easier to order online bc I know the size at home and I use the subscription so I don’t forget to change the filter. Better price here than in stores near me.

These Filtrete 20x25x4 AC Furnace Air Filters are massive — I didn’t even know filters came this big until I had to replace the one in the house I bought. The size caught me off guard, but installation was super easy, so that was a relief.The quality is great, and I can tell it’s doing its job in keeping the air clean. The MERV 12 rating and MPR 1550 mean it’s catching more particles, and I’ve definitely noticed improved air quality. The cost was a little high, but since it comes as a 2-pack, I feel like I’m getting decent value. I’m happy with the performance and how easy it was to install.Key Features:Large Size: Fits perfectly in larger systems like Lennox & Honeywell.High Filtration: MERV 12 and MPR 1550 offer excellent filtration for dust, allergens, and particles.2-Pack Value: Comes with 2 filters, which helps justify the price.What I Love:Easy installation, even with its large size.High-quality filtration that noticeably improves air quality.Comes as a 2-pack, so I have a backup when it’s time to replace.What I Don’t Love:Cost: It’s a little pricey, but at least it comes as a 2-pack.Size: The large size was surprising, but it fits perfectly for the system in my home.If you need a high-quality filter for a larger HVAC system, this one fits the bill. It’s big, but it installs easily, and the 2-pack makes it feel more worth the cost. The air quality in my home has improved, and I’ll definitely keep buying these for future replacements.

These filters appear to work well, MERV 12 should give pretty good pollen protection, and I keep them in for at least 6 months.

I needed the 20x25x4 air filter. It fits perfectly, almost too snug, but so much better than the narrow ones. It’s easy to install. I prefer the higher rating, so allergens are protected. Great value for the money in my opinion.
