AprilAire 413 Replacement Filter for AprilAire Whole House Air Purifiers - MERV 13, Healthy Home Allergy, 16x25x4 Air Filter (Pack of 1)

Fits my Carrier unit from Coolray. Durable, sturdy, worth the price. Cheaper than going through our maintenance plan,

Grabbed the two-pack when the old 413 was due for swap, and these are genuine - solid frame, slid into the housing exactly like the original with no trimming or forcing, and the pressure reading on my unit hasn't budged, so no air is sneaking around the edges. Two and a half months in, no change in house air quality or system behavior. Buy the genuine listing, not a marketplace one; the "used filter" complaints in the reviews are about sellers, not this product.

These filters fit perfectly and we love this brand. They were cheaper than some other sellers.

Pricey, but worth it to keep the air clean.

TL;DR: I use it. I will buy it again. I recommend it. My 4 stars means 'great product'. (Please note: I reserve 5 stars for over-the-top outstanding; if everything gets five stars it becomes meaningless. My 4 stars is everyone else's 5 stars - it means the product is good, I'll buy it again, and I recommend it. It's does just what I *expect* it to do; no better, no worse. I do the same with standing ovations at plays and live performances, btw... Usually I'll know within a few minutes it deserves a standing ovation; it's beyond expectations.) My favorite way to evaluate something: if I knew then what I know now, would I buy it? This filter: Yes. I would, and will buy it again. I recommend it without reservations. How I installed the filter: Open Amazon package. Pull down attic hatch, unfold ladder steps. Climb up ladder. Forgot filter, have daughter throw filter box up ladder. Miss. Repeat; catching box this time. Crawl over to air conditioner (low ceiling in attic...) Open filter box. Lift cover off air conditioner. Slide old filter out. Ick! Full of dusty and crud. (we got the 410 filter last time; better 413 this time) Open new filter box, slide filter out of it. Pull apart to open it. (accordion-like) Slide bottom piece (slightly) onto air conditioner. Bump nearby chimney so it falls off (filter from air conditioner; the chimney didn't fall off) Slide bottom piece onto air conditioner again. Slide top piece onto air conditioner. (being careful not to bump the chimney again) Push both pieces to slide filter into air conditioner. Slides right in, fits perfectly. (410 did too) Replace cover over the filter. Crawl back to ladder. Toss empty box down to daughter. (don't toss old filter unless you want an upset dust-covered daughter!) Crawl back down ladder, carefully carrying old filter. Put old filter into trash bag. Fold ladder steps up, push attic hatch closed. Put trash bag with old filter in garage. (awesome daughter already put new filter box into recycling bin) Wash hands. Congratulate self on doing a wonderful job. Family stands around smiling and applauding; bask in their adulation. (not didn't happen... - but congratulate self and cross off the 'to-do' task) It took longer to write this - and probably for you to read this - than it took to actually change the filter. Air conditioner is immediately working better - cycling quicker than before. I can't actually tell, but I'm sure our air is cleaner. (that's not a reflection on the filter; more on me...) Make a note to change it again in six months or so. Cheap and easy way to keep the air conditioner working better! Summary: I use it. I will buy it again. I recommend it.

Good quality & easily fits furnace. Arrived very quickly. Look for arrow, or install same as the one you remove.

Did what was needed. Nice product

We were looking for an alternative to buying an air filter for our furnace and AC unit. The one that we were gonna buy from Kinser and Kinser was like $30 more than this item and I can have it. Auto shipped to the house as often as I need just a perfect option so that we can make sure our furnace and AC unit are well maintained

I bought this as a less expensive option, compared to the filter that is sold by the company that installed my furnace, the KMRF001 filter. It fits great! There seems to be a little bit more room after this filter is installed, compared to the original one from the furnace installer, but it still works great, and it's easy to install. The quality of this filter is very good, and it does a great job of keeping dust particles out of the air. My wife is very sensitive to dust, and there was a noticeable improvement with the air quality in our house after installing this filter.

I got the 4-pack, much better price per filter than buying one.

Not as expensive as the name brand and works fine, good enough for me.

These are the OEM filters for various AprilAire furnace filter systems. I've used these exclusively, and have never had any problems. While they are somewhat expensive, the filters last about 6 months, so the $10-12 per months that it ends up costing is worthwhile to help keep the air clear for our kids.

Great product. Great price. Perfect fit.
