Aerostar 16x25x1 MERV 11 - 6 Count - Pleated HVAC, Furnace & Air Conditioner Filters - Removes Dust, Cold & Flu Germs, Lint, Mold, Pet Dander, Allergy-Causing Pollen, Smog & Smoke

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!

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".

Works great as advertised. Just be on the lookout for single sheets of paper/ plastic wrap between the filters that might ride along unnoticed and find their way into your furnace’s blower motor. Just run you hand on both sides of the filter just to make sure there isn’t anything there that shouldn’t be.

I use these as my normal a/c filters. Have never had a problem with my unit using these. I have 1 dog and 1 cat. During the hottest months I change out once a month, but during coolest months I only change out every 2-3 months. Don’t use the unit too much for heat. Very comparable filters!!!

These are very good quality filers. Also it's not expensive. It fits well as per the measurements.

Work great and great fit

Value n convenience. We have pets and our filter is always needing chgd. It’s convenient to have one at the ready n not have to shop every few months

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 is the "size of the filter" you need to match that up. What you need to also understand with these cardboard disposable filters is that the DEPTH measurement will not be the same. SO---The filter saying you need a 19 7/8" filter by 21 1/2" by 1" will fit the filter that is listed as such. What you will get delivered is one that is 19 7/8" by 21 1/2" by .75". That doesn't make it undersized lol. That's what you get. If you go to a big box retailer that's what they will have too. If you make sure the manufacturer size is what you got for the first two measurements, the 19 7/8" by 21 1/2",,,,,,the filter you get will be EXACTLY that. It is thinner at .75" though. THAT IS NORMAL. Measure one at big box stores, this is how it works. If it's too small, you ordered the wrong one in the first place/not shopping the right size.Second: I am thoroughly impressed with the top of the filter (where it has the cardboard going across in a diamond shape type pattern. I should have provided a picture of other competitors but this one is matching similar structure/strength as the big name brand ones. The ones I have been using (a diff brand than these) for the last 6 months, are definitely lesser quality and I can see that.Third: I change my filters every 60 days, have it written on my planner and a calendar reminder. These will do the trick, the quality is awesome and last just as long. The resistance for air flow appears to be spot on the merv rating in which they provide.Fourth: The packaging. These came in PERFECT condition. Keep in mind they are really thin chicken wire type skeleton as they all are. The way it was packed, there was no phsyical damage that will have any measurable impact on the effectiveness of this filter.I am really impressed and pleased. A great buy for the price. I have NO problem recommending these filters to people. I am sure for far more money and a very technical analysis I could come up with better options but again-----in this price range, and what you actually get delivered -I couldn't be happier. Great value for the money, for those that change them every month, there is no reason to spend 12-30 dollars a filter. Just get the correct merv rating for what you need, make sure the width and length are the RIGHT/Correct measurements. And you are set!

Great filters, good value

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.

While these appear to be a pretty good filter at a good price buyers should be aware that while its advertised you will get 6 filters and the box when you receive it is labelled as having 6 filters inside, in fact what you get are 5 filters. Still a pretty good deal but surely a bit of false advertising. By reading through the reviews it appears this is not the first time this has happened. Just not worth the time and hassle for me to make an issue about it. My last time buying filters here though.

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.

I don’t know if only me have the problem with these filters. They are good filters if they are not received damaged. The shipping box has no damage to it, but the filters are damaged. Same as I bought from two years ago. I think the manufacturer sent damaged filters to amazon to sell them for a cheaper price. Because I’ve ordered one for my brother and one for myself from the manufacturer last year and this year, those filters have no damages at all, and the shipping box has the manufacturer name and logo on. But the ones I bought here don’t have that, other than having damage.
