Air Filters

Grainger has air filters for industrial and consumer applications to clear the air. Install a permanent electrostatic air filter that needs no hookup and generates its own charge. Purchase a hospital-grade, UL Class 1 HEPA filter with 95 percent efficiency that eliminates potential air leaks. Or, for fume and odor removal, choose a carbon filter set that is disposable, eliminating the need for refilling. Grainger has air filters that help you keep indoor air clean, comfortable and safe.

Answer: 
Alessio,
Grainger does NOT sell parts for mini-split units Sanyo. This filter-kit STK-ARF4B is optional for the unit KS1251, the KS1251 came with a washable filter that under my experience works well, but you have to keep it clean, even if you buy the optional. The optional it's a secondary filter and it's NOT washable it's disposable, the kit STK-ARF4B came only with one filter, so you have to buy: the kit STK-ARF4B and filters STK-F4B. Call a Sanyo mini-split A/C dealers, they are the only ones that sell this kit.

Answer: 
Belvedere,
Yes, Grainger carry 24" x 24" x 1" filters, but when you are asking for a filter also let Grainger know what kind the filter do you want, there is so many kind of filters on the 24" x 24" x 1" size (fiberglass, pleated, metal,.....) the most popular is the Pleated Standard, that will works good on your home or office, also if you order on case of twelve (12) you will have better price and don't worry for a year. Even if the filter say 90 days change every 30 days, because the conditions where they lab-tested are not the same that you have.

Answer: 
Phippy,

When you order a filter the actual size is 1/4" to 1/8" less that the standard size, it will allow the filter get in and out easy, this may be a filter 20" x 25" x 5" and because is 5" it has to be one of the new kind of filters that we call "Media Filter" but is NOT like a standard size 20" x 25" x 5", it will NOT fit good! I'm sure it's a media filter and may be manufacture by Aprilaire or Honeywell, because they make the most popular home media filters; others could be Flanders Precision , Air Handles or Purolator.
Look for the number on the filter and the brand of your media air cleaner, if could be electronic cleaner or not.
Do not order a special filter made 19-3/4" x 24-1/4" x 4-7/8" the paper is different, technically talking it has a different "MERV" .
