Our take on the UBeesize 18 x 20 x 1 Washable MERV 8 Electrostatic Air Filter

This is a reusable 18 x 20 x 1 inch furnace filter from UBeesize, rated MERV 8 and built with an electrostatic media that traps dust and pollen without adding much airflow resistance. Instead of replacing it every few months, you rinse or vacuum it and put it back. The best new price is $44.99 at Lowe's as of November 7, 2026, with two stores listing it new.

Best forOwners tired of buying disposable filters every seasonHouseholds with pets or light dust and pollen concernsStandard 18 x 20 x 1 return grilles and furnace slotsRenters who want a low-maintenance filter
Pros
  • Washable and reusable, so no recurring filter purchases
  • MERV 8 captures dust, lint and pollen while keeping airflow high
  • Standard 18 x 20 x 1 size fits most return grilles and slots
  • Electrostatic media holds particles without a powered unit
Cons
  • MERV 8 will not catch fine smoke, bacteria or virus-sized particles
  • Needs regular rinsing; a clogged reusable filter strains the blower
  • Reusable filters can shed fibers or degrade if washed roughly
  • At $44.99 it costs more up front than a single disposable filter

Questions and answers

Is a MERV 8 filter enough for a home?
For most homes, yes. MERV 8 handles dust, pollen, mold spores and pet dander, which covers typical residential needs. Go higher only if someone has allergies or the HVAC system can handle the extra resistance.
How often should I clean it?
Check it monthly and rinse or vacuum it every one to three months, depending on pets and dust. Replace it when the media looks matted or torn.
Will it fit my 18 x 20 x 1 slot?
It is made for nominal 18 x 20 x 1 openings, the most common return grille size. Measure the slot before ordering, since actual filter dimensions can run slightly under nominal.
Is it cheaper than disposable filters over time?
Over a few years, usually yes. At $44.99 it costs more than one disposable, but it replaces several per year, so the break-even comes within roughly a year or two of normal use.
Does it reduce airflow like a high-MERV filter?
Less than MERV 11 to 13 filters. MERV 8 is a middle rating that keeps static pressure low enough for most blowers, though a dirty reusable filter will still cut airflow.
Where is the UBeesize 18 x 20 x 1 Washable MERV 8 Electrostatic Air Filter cheapest?
At Lowe's, for $44.99, as of our latest check.
Where can I buy the UBeesize 18 x 20 x 1 Washable MERV 8 Electrostatic Air Filter?
2 stores we checked sell it, including Tractor Supply Co, Lowe's.
