Quick delivery. Product seems to be of the same quality of other brands. Purchased a few filters. Only thing I would rather each filter be wrapped for later use.

Unlike other furnace air filter Aerostar 18x20x1 works excellently and easy to install. The size is perfect and instructions makes it is very simple to locate the up arrow which usually is hard to locate. I buy these filters twice a year and pricing does not hurt me.

Great filters but holy tamole! Talk about inflation! Or maybe just price gouging??
Last time I purchased this 6 pack from Amazon on April 8, 2019, they cost 28.49.

10/10 would buy again.

Clean air for your home, health, and pets is important and something you should never have to worry about or compromise. Accessibility to the correct, high-quality air filter for your HVAC (heating, ventilation, and air conditioning) system should be easy and painless; something you can bookmark or note and save for each time you need to order refills.

This pleated replacement air filter delivers clean air by replacing your air system's vent intake filter. It is designed to work with most home and office AC and furnace systems with compatible and custom intake vent sizes, filtering out dust, pollen, bacteria, allergens and micro-allergens, and other airborne particles to deliver great indoor air quality and odor reduction for healthy living.

This particular brand and construction is reliable, impressive, and high-quality as they state and I am pleased with its performance (which you can tell when it's time to replace the filter and you see just how much gunk it caught and saved your system and you (and your pets) from inhaling.

I change my air filter once a month then re-order when I've used all 6. I was already familiar with the Aerostar brand and this product from having previously ordered and used them. I last ordered my replacement 6-pack from Amazon on Friday, April 28th, 2023.

I have now used a total of 7 of these, and air filters in general are usually more expensive.
Amazon turned out to be the best value with the 6-pack being $67.90 (+$5.09 tax = $72.99 total cost), in-stock and available, which I was willing to pay for the convenience and Prime 2-day delivery and return policy.

I personally vouch and advocate for and recommend this air filter from personally and consistently seeing such satisfying results after many months of use now. I will continue to order it from Amazon when I need replacements. I do not think you will be disappointed with the results!
