Why FilterBuy Air Filters?
Long-Lasting
FilterBuy filters are designed to last up to 90 days, 3 times longer than fiberglass filters. If you have pets, kids, or allergy sufferers in your home or business, replace your filters more often to maintain superior indoor air quality and keep your energy costs low.
Made In The USA
All air filters are manufactured by FilterBuy in the USA using 100% American made components. By purchasing directly from the manufacturer, you’re saving big on a premium product.
High Quality
19.75x21x1 pleated air filters are at least 20 times more efficient than fiberglass filters. Filter frames are made of beverage board, which stays strong through humidity and temperatures up to 200° F. Synthetic media provides significantly higher particulate efficiency than standard cotton media.
Have in the past had difficulty finding filters to fit exactly. These fit great!

It's too soon to review
I've only had the filters installed for a few weeks, so it's not possible to write a detailed review.
However I can say that the construction of the filters are impressive. All previous filters I've used were "flimsy" - these filters are absolutely solid.
I'll write another review in a few months.

Just upgraded to a better filter from filterbuy. I wanted to test the draw on the AC system with a higher rated filter. I am very pleased with the results! The system does not seem stressed from greater filtering. I am hoping it will have an added benefit of keeping dust levels down .

Is it Time to Change Your Filter?
Generally, we recommend you replace your air filters every 90 days. Find out below if you should change your filters more often.
If someone in your home has asthma and/or allergies...
Change your filter every 6 weeks to ensure indoor air quality is at its best.
If you have pets...
Change your filter every 2 months to avoid shedding and odor buildup.
If you have young children...
Change your filter every 2-3 months, as having clean air is even more important with children in your home.
Simply measure the length and width of your filter with a tape measure and choose the closest size
(to 1/8”) in the drop down menu. 1/8” tolerance is standard and should not cause a problem in any
standard filter application.
Please note that the ‘actual’ filter size, ie the size that your tape measure shows, should be used when
creating a filter with this tool, not a nominal filter size. Note that the depths of each filter are
standard, as shown to the right.
