Genuine AprilAire 413 Replacement Filter for AprilAire Whole House Air Purifiers - MERV 13, Healthy Home Allergy, 16x25x4 Air Filter (Pack of 8)

Great product, I buy them frequently, they are reasonably priced and easy to install. I change them about every 4-5 months and they look pretty dirty so they are doing a great job at filtering.

Pricey, but worth it to keep the air clean.

I love getting things like this from Amazon. Nitnis easy to know when to replace based on previous order and then to add it for Auto ship so you don’t forget to replace on time. This is durable, good quality and replacement is easy to do. Appearance? It is a filter. Not much to look at! But does a great job.

This is a great filter for our HVAC. It is cheaper to buy from the Amazon store versus paying our HVAC maintenance company for it. This is a on going purchase for us. Highly recommend.

It is as advertised. Comfortable, but not top of the line.

Overall great product for use in hvac systems. Fit nicely into the unit with no issues.

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

Expensive replacement but great product

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.
