This filter seems fine, but an inch or so from each end there was glue between most folds causing me to have to carefully separate the folds to break the glue (or slightly rip the filter material). Not bad enough that I'd take the time to return, but in the future I'll go back to the Aprilaire distributed filters because I've never had an issue with any of the five I've used from them.

I have been using these filters for 15 years, since I replaced my furnace. I considered both the standard filter with no pleats and the electronic filter that requires cleaning with soap and water. I choose the Aprilaire and have been happy ever since. I believe it extracts more debris than the electronic unit and doesn't need changed as often as the standard non-pleated unit.

I just changed my furnace filter today after a six month heating season in upstate NY and now am ready for the six month central air cooling season.

Bottom line ... This filter is exactly the right place to be for me, so I give it a definate 5 stars.

An exact OEM fit for my Aprilaire 2400 whole house filter. Installation is clumsy, but that's hardly the fault of this media. Of better quality and construction than the knock-off units available at big-box hardware stores. Completely satisfied.

The genuine aprilaire filters are expensive, and so I hoped to save money by buying these supposedly compatible filters instead. As you probably know, they are the "accordion" type of filter with lots of folds along the edges. That's the problem: these inferior Mexican-made knockoffs made by "Healthy Climate" have tears in the seams which will allow the unfiltered air to get into your HVAC unit, and then on into the air of your house! These filters have what feels like metal "ribs", and that probably is what causes stress in the manufacturing process resulting in the tears.

You don't get to discover these flaws (and I found over a dozen such seam tears in one filter alone) until AFTER you open the box to get a replacement. I have taken nylon-strand tape and repaired the tears, and that was quite a job. I don't know if the adhesive in the tape will survive the air blowing over it or not.

I know the genuine Aprilaire filters are expensive, but these Mexican "POS's" aren't worth a penny if they don't do the one thing they are supposed to do: FILTER THE AIR! I'll never buy a knockoff filter again!

I'm thrilled that Amazon now offers these filters. My A/C service company charges $50 for these during their annual maintenance visit. Thanks to Amazon, I now have the replacement filter waiting for them prior to the May cooling check.

I've installed this filter myself as well. It's tedious, but easy after the first time. My filter has five combs -- to start, you just have to match each spike up to a pleat to properly space out the pleats of the filter. Once you do the first one, and the pleats are properly spaced, just place the second comb right next to the first one and then slide it down the filter. Repeat for the other three combs.

Fortuantely, this only has to be done once per year.

Excellent purchase - I received the filter as shown (aprilaire in the box shown). This is a much cheaper option than buying it from the furnace/a/c cleaners.

Factory original filter from aprilaire in aprilaire box. Nice to see you can still get factory original and not a spinoff replacement.
