Product Description

Aerostar 12x12x1 MERV 11 Pleated Air Filters (Actual Size: 11 3/4"x 11 3/4" x 3/4") - 6 Pack. MERV 11 filters are comparable to MPR 1000-1200 and FPR 7. Designed for superior filtration efficiency, these filters are made with electrostatically charged synthetic material that draws and captures allergens between 0.3 - 1.0 microns, including lint, dust mites, spores, pollen, pet dander, fine dust, and smoke. Aerostar filters are a simple and cost effective step towards a healthier home environment, free of airborne allergens and particles that can trigger various allergy and asthma symptoms. They also improve the efficiency of your HVAC unit and therefore reduce maintenance and utility costs, by removing dirt and reducing strain on the motor. For best results, change the filter every 60 to 90 days but increase frequency to 30 days during peak summer and winter months when your unit is working the hardest. Compatible with furnaces and AC units.

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!
