    • Aerostar vs. 3M Filtrete Micro Allergen Defense
Size: 20x20x1 Pattern Name: Filter
Review Image by Bob Bob
Review Image by Bob Bob
I purchased these filters instead of the Filtrete Micro Allergen Defense filters I had been buying previously since the 3M filters have gotten way too expensive. Overall, these filters are better in many ways than the 3M filters but fall short in one respect. Pros: the Aerostar filters are better supported than the 3M filters (see photos), heavier (8 oz. vs. 7 oz. for the 3M), and have more pleats. The generally feel more substantial and rigid than the 3M filters. Cons: they are smaller than the 3M filters and may fit more loosely depending on your ductwork. These filters are 19.5 x 19.5 x 0.75 inches while the 3M filters are 19.7 x 19.7 x 0.75. I used foam tape along the edges of my return ducts to make it a tight fit. Considering the price difference and the overall better quality of the Aerostar filters, I will certainly buy them again. Photos: 3M filter is on the left (somewhat dirty since I was replacing them), Aerostar filter is on the right. ... show more

    • BEWARE!!!
Size: 24x24x4 Pattern Name: Filter
Maybe I'm just being overly picky. I received the 6 filters I ordered in a plain brown box. OK, no problem. But upon inspection of each filter I noticed none of the filters indicated the MERV rating. This is the first time I've ever purchased filters (regardless of brand) where the MERV rating is not clearly indicated on the filter. So, I have no way to verify that what I purchased is what I got. Quite frustrating... ... show more

    • Non-standard, under-sized filters
Size: 20x20x1 Pattern Name: Filter
I order a box of filters at a time. So, with only a couple filters left from my last purchase I ordered these, an upgrade to a MERV 11. Well, I went to use one and noted that the first one I pulled out of the box of 6 was crushed/mangled in the corner. I should have noticed this when it was delivered. But when I went to put another one in my vent, it did not fit. Most 20x20x1 filters are really more like 19.75 x 19.75 x.75 but this one is 19.5 x 19.5 x .75 and it means I have a one inch gap to fill on two sides when I insert it. Not happy. My window to return this was 5 days ago apparently. ... 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

Affordable, great quality, and my go to brand! I buy these every few months and they are great. I replace three of this size and one larger every 2 months. We keep our house clean and dust free at all times, but we live in a state where allergies are constantly brewing and can't escape it. These filters help!!! Results you can see and feel. Only con I have is that these are a bit short and fit loosely. My solution is a $1.50 roll of window weather stripping around the filter and I get a snug fit. Overall, I'm happy and will continue to purchase. ... show more

    • Filter is too strong for my HVAC, never happened before
Size: 20x20x2 Pattern Name: Filter
So, this was odd. I started smelling a burning smell from my HVAC unit, even when just the blower was one, no AC. The guy came out to check it out, said nothing was wrong. Finally it hit me, I had bought new filters a few months back, and had just started using them. So I borrowed a MERV 7 filter from a neighbor, mine are MERV 11, and the smell stopped. I just checked some professional tests online and it seems different filters, of the same MERV, cause a different pressure drop on your HVAC unit. I've alway used MERV 11 in the past because I have allergies, but for whatever reason, this brand's MERV 11 appears to put too much of a strain on my HVAC. And now I'm stuck with multiple filters I can't use. Be forewarned. ... show more

    • Great deal - a bit small
Size: 20x20x1 Pattern Name: Filter
Stoked to find this six-pack for roughly $30! We're impacted by a huge wildfire, and smoke affected our air quality terribly for two weeks. Grabbing these MERV 11 filters at this price made us able to change them frequently for much less than the $15-20 each price we were seeing at local stores. Note: They run small. About 1/4" shorter than the 20x20 size indicated. Not a deal breaker, but air was able to go around them, bypassing the filters altogether. For a quick fix, we ran some packaging tape around the edges to close the gaps and force air through the filter. That's the only reason for 4 stars. ... show more
