Aprilaire Replacement Filter for Aprilaire Whole House Air Purifier Models: 1510, 2516 Single Pack (1) 510 A1 1

While expensive, this filter came exactly as advertised and is OEM, which I like. It appears to be very well made and of high quality. I expect to receive better air quality in my house as a result.

Because of hte size of the filter, I only have to change 1 filter in my system every 6 months. This works great.

Perfect fit! I love how compact it is and how it expands like an accordion and slides right into place. And very, very functional! Love this brand of filters.

We like this filter since it does a good job filtering the air in our house.

Fit our A/C unit perfectly. These are required by Carrier for our units and the A/C installer said these will certainly not negate any warranty issue with the unit itself. Very easy to install by a homeowner. There is no need to have a tech put these in unless you have access or a personal issue that would prevent you from changing the filters. A high price for what they are made from but your A/C will work as designed and probably allow the units to function as designed for years to come, saving repair costs later on. If these are required by the manufacturer, do not substitute with some inferior brand to save you grief if you have a warranty claim. I was able to change out 3 of these in about 10 minutes total.
