AprilAire 213 Replacement Filter for AprilAire Whole House Air Purifiers - MERV 13, Healthy Home Allergy, 20x25x4 Air Filter (Pack of 2)

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.

We have had good results with this filter. The last one lasted almost a year! Checked on a regular basis... Quality product.

Why did you pick this product vs others?:We have used this several times. It is easy to install and a great buy.

Fits perfectly and does a great job filtering dust and allergens. I notice cleaner air and less sneezing. Easy to install and worth the price for better indoor air quality.

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.

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.

I find these filters very helpful in keeping the house cleaner. We have a dog with a lot of hair and the filter works very well. We checked it the other day and it is working perfectly. We should be able to not worry about changing it until this fall. Easy to install and maintain.
