    • BASIC has a rating of MERV 5
    • The higher the MPR, the more microparticles - such as pollen, pet dander, smoke, bacteria and viruses -- your filter will capture from the air passing through it
    • A dirty filter will slow down air flow and make the system work harder to keep you warm or cool -- wasting energy. Sign-up for a filter change reminder program (www.filtrete.com/ChangeReminders) that works for you!

    Filtrete™ Basic Air Filters is rated 3.4 out of 5 by 83.
    Rated 1 out of 5 by from Poor fit I purchased 20x30x1 filters for my 2 HVAC systems and tried to install them in factory manufactured return air grills. I removed the old 20x30x1 hardware store branded filters and attempted to install the new Filtrete basic ones. They were so tight I had to force them into the opening causing them to bow, allowing the air to go around the filters. I ended going back to the hardware store and purchase the cheaper brand that fit properly. I had this same issue at another property I own. Picture it the filter that fits correctly.

    Rated 1 out of 5 by from Wish frame was full. I wish the frame on these filters was full instead of being so thin. It does make a difference, especially noise-wise when the unit comes on and turns off.

    Rated 4 out of 5 by from Good Filter My husband came home with this air filter. I changed it out and watched it over the last month. It works good. A little heavy in thickness so not sure how well it filters through but it does the job.

    Rated 1 out of 5 by from Not true to size I bought two different sizes (12x24x1 and 16x20x1). Both sizes are slightly larger than the size stated and will not fit in the openings. Very poor quality.

    Rated 4 out of 5 by from Restricted Air Flow Why is there so much cardboard restricting the airflow? I remove all crisscrossed cardboard from the middle of both sides and they work fine with better airflow.

    Rated 3 out of 5 by from New Design? I bought my filters from lowes as usual and was confused about the direction of the arrow. My old filter arrow goes towards the metal side and my new filter arrow goes away from the metal side. I thought the point of the metal or wire mesh is to ensure the cloth doesnt get sucked into the vent/intake. Ive wasted a lot of time trying to research wire down or up and didnt get much info except to follow the arrow. (What if the manufacturer made a mistake?) Id like to think that the manufacturer would be proud of their design change and proudly display and gloat about its advantages on the package or website. Nothing. I happened to find another comment like mine with a response attached stating that indeed the arrow direction is correct, the wire does face me, and the new design has been tested numerous times. I gave this product a 3 star not because of its quality but because of the struggle to find info and my lack of trust in the direction of the arrow. Afterall, ive been having the wire side face away since the beginning of time.

    Rated 4 out of 5 by from better air flow Installed this filter two weeks ago and have seen a definite improvement over the better rated ones, seems like my a/c has shorter run cycles and my house is as cool as before. I will use this level of filter from now on. Also the last two weeks we have had record setting temperatures almost each day.

    Rated 5 out of 5 by from Good filters - people need to stop second guessing I've always wanted a decent filter that allowed for superior air flow after pleated filters pushed the old fiberglass filters out of the market. These excellent, inexpensive, free-flowing filters are perfect. Several reviews here are complaining about the airflow arrow being backwards. Just follow the installation instructions, don't second guess the engineers, and you'll be fine. I've been using these for years in my own home (two air handlers, four filters) and two rental units (one air handler each). Never had a problem. They work well, they're light but durable. And they definitely improve heating/cooling efficiency over the restrictive filters most people use now. Worth noting that studies done on HVAC air filtration show that no matter what kind of filter you use, you don't get most of the dust in your house anyway because it's resting on surfaces and embedded in carpets and pillows. So no matter how high a MERV rating you use, you end up breathing all the dust as you move around the house stirring it up before it ever gets near your filter.
