Jgpapillon: I have to replace my filters every 6 months and these are easy to install and are cheaper than what I could find (if I can even find them) at Lowes or Home Depot. They are not cheap but nothing is these days....

Robert: I get the six-pack of these because I know I'm going to use all of them over time and and they're the tallest I can get to fit into the opening. The increased filtering area helps me avoid having to change too frequently or wonder if my airflow is being restricted. They're easy to install and fitment with my furnace is perfect with no gaps, and they appear to perform well enough to use for 2 months at a time with no perceptible decrease in filtering performance. I have a dusty horse arena and 3 house pets (2 large dogs and a cat) on the property and we breathe easy in our house with these filters installed.

Chris MontanariChris Montanari: 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...

J. Fraser: The Aerostar MERV 11 Pleated Air Filter, AC Furnace Air Filter, 6 Pack is a good value and a decent filter. It does a good job of filtering the air, but they are slightly less rigid as some of the premium brands. Humidity can affect the longevity. I have used these for several years and recommend them. I moved down from the more expensive premium brands, and these Aerostar filters do get the job done. Because of their lower cost I tend to switch them out a little more often, but they will last 3 months without issue.

High Merv values will generally last less than lower, I have found, as they tend to get clogged up with dust sooner allowed less air to pass through and cause the fan to be less efficient because of the increased back pressure. This is not this brands problem; it is all filters so be careful when selecting high Merv. I tried several different and found MERV11 is about a high as I would want to go. (for me) "but your milage may vary".

D: Received quickly. I've been using the Aerostar filters Merv 11 for two years. I have used other brands and I have discovered that the Aeorstar cardboard frame is more sturdy than cheaper brands or even common store brands like 3M. My furnace and A/C has a very powerful 2-stage fan that will cause cheaper/flimsy brands to become warped which allows dust to pass by the filter. The Aerostar filter is more effective at capturing dust and I change them every 6 to 7 weeks. If I leave them in for longer, the filter becomes clogged and dust starts to escape around the edges. At roughly $15 per filter it is worth it to change them more often and keep your house really clean.

Lsi: I've ordered these a few times, and their quality is decent but packaging quality has gone down (box needs to be split open to remove a single filter) and pricing has gone up with each order to ridiculous levels now--nearly 2.5x its original pricing.

Pricing is now higher than a conventionally-sized Nordic Pure filter sold here with activated charcoal and much higher filtering quality. I will be looking elsewhere for future orders in this sizing for Carrier furnaces, unless pricing improves.

EvanEvan: Ok. So I am VERY particular on things like furnace filters. It drives my wife nuts how much I get focused on research for car waxes and furnace filters and even the chemical needed to clean the outdoor AC Condenser fins lol. I rarely post reviews but I wanted to make this very basic to cover what my wife says is important and what my reluctance-concern was when I submitted order and had hope many of the reviews were wrong on...

First: The filters are NOT undersized. There are two things to look at on furnace filter sizes. The first thing is make sure you have the correct filter size to begin with! I can't tell you how many times I have talked to people (My brother in law owns a large HVAC company) at his company picnics etc that just flat out think there is no difference between a 20 3/8" filter and a 20" filter. You need to be sure direct from the manufacturer-that you have the exact sizing of the appropriate filter. Number two is they have two sizes listed in the product listing. This is true for 3rd party filter websites, Amazon, other retailers. The first is the "size of the filter" and then the "actual size of the filter". You need to realize that the manufacturer size...
