    • Great value
Style: 20x25x1 Pattern Name: Filter
I am a repeat purchaser of the Aerostar 20x25x1 MERV 11 Pleated AC Furnace Air Filter 6 Pack, and I continue to be very satisfied with my purchase. This pack offers great value, providing a year-long supply of high-quality filters for our HVAC system. The MERV 11 rating is perfect for capturing a wide range of airborne particles, including dust, pollen, and pet dander, which helps maintain cleaner air inside our home. I change the filter every couple of months to ensure our HVAC system runs smoothly and efficiently. Each filter is sturdy and well-constructed, fitting snugly into the unit without any issues. Since using these filters, I've noticed a significant improvement in air quality and a reduction in dust accumulation around the house. The pleated design maximizes surface area, ensuring better filtration and longer lifespan compared to flat filters. Additionally, the 6-pack offers excellent value for the price, effectively covering our needs for an entire year. This convenience means I don't have to worry about frequently purchasing filters, and I can always have a spare on hand. Overall, the Aerostar 20x25x1 MERV 11 Pleated Air Filters are a great investment for anyone looking to maintain their HVAC system and improve indoor air quality. ... show more

    • These are amazing. Take prior comments around undersized/packing, with a grain of salt.

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! ... show more

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! ... show more
