AprilAire 213 Replacement Filter for AprilAire Whole House Air Purifiers - MERV 13, Healthy Home Allergy, 20x25x4 Air Filter (Pack of 1)

We always purchase the AprilAire 213 for our unit and are happy with the performance. The price on this was better than what I've paid from other online filter sellers so that was a big plus! Filter arrived as expected in good shape.

Always fits, easy to install, works great

Fits our AprilAire filtration unit very well and filters as expected. It is a great value because my house is much, much less dusty that before our April Aire was installed, and this exact filter is much more expensive from my HVAC company. The HVAC company that installed & services our heat & AC unit suggested we buy it on Amazon.

I change mine every 3 months or less. Having pets gunks um up. Perfect replacement for my system. 5 years no issue.

I recommend this product though I have not yet used. At the time I purchased I could not find anywhere outside of the installer whom was playing the proprietary game. These are the higher end (I believe 217 is the highest type) to those the installer supplied (210s) at a lower price. Would buy again and recommend to anyone having trouble sourcing locally.

Easy to install...sort of...it's a bit of a game getting the grooves on the top of the filter aligned at the same time as the bottom ones, but once you've got it, you're good to go! I'm amazed at how much gunk they filter out and how thick these are. They surely trap all the rotteness that gets into the air to save your lungs. I love how fresh the air in the house it. It's hard to believe these last a year! So while it seems expensive, you're getting so much more and who wants to climb up into the attic multiple times a year? This is a far more efficient way to go.

These air purifiers are a more affordable yet highly effective option for my air conditioning unit. They fit perfectly and perform exactly as expected

Excellent Product. We get it a good price from Amazon compare to Amazon and it gets the job done. It’s easy to install and fits perfectly in our ac vent. It helps keep the Ac running efficiently for nearly 6 months.

Excellent filtre

I’ve been using this furnace filter for a few months now, and I’m genuinely impressed with the difference it’s made. The air in my home feels noticeably cleaner, and I’ve seen a huge reduction in dust buildup on furniture. It fits perfectly, installs easily, and does a great job capturing allergens and pet dander—which is a big plus since I have pets. I also appreciate that it lasts as long as advertised, making it a reliable and cost-effective choice. Definitely recommend this if you’re looking to improve your indoor air quality!

Arrived early. Exactly as described. An OEM item, so it fit perfectly

It is unfortunate that these are the type of filters that I have to use for my house because they are quite expensive compared to other filters/furnace systems. But aside from that, it is easy to install, and I guess does capture dirt very well, it's just quite expensive. My suggestion: if you see a reduced price, make sure to stock up that will last you a couple of years.

It works as expected. It’s a furnace filter.
