2-Pack of Applied Biochemists® Filter Blaster was designed for the busy pool professional, Filter Blaster cleans cartridge and D.E. filters in only 5 minutes. When you don’t have time to soak, this spray-and-rinse formula removes scale, grime, grease and other filter-clogging debris fast. 

Filter Blaster Features

  • Easy-to-use spray formula
  • Removes grime with powerful detergents & mild acids
  • Removes rust, oils and other filter clogging debris

Normal Application 

Remove cartridge or D.E. filter from housing. Rinse off any loose material and completely saturate the filter with water. Spray Filter Blaster over the entire filter surface area . Allow to soak for 5 minutes and rinse clean with garden hose. Heavily soiled filters may require a second application. If possible, let cartridge filters dry before reinstalling. This allows the fibrous material to "fluff" allowing filter to capture material most effectively.


Always start out the season with a clean filter. Use Filter Blaster during the season to keep your filter working a peak efficiency. Maintaining your filter will reduce chemical consumption and result in consistently cleaner, clearer water throughout the season. Filter Blaster is safer to use than muriatic acid.


Effectively and economically removes grease, oil and mineral scale deposits and dirt from filter elements in just five minutes.

Compatible With

Chlorine, bromine, ozone and biguanide sanitizers.

    Easy and fast

    This product has been used for cleaning our pool filter for years. It's now 17 years and they have never needed to be replaced. Just cleaned every 3 to 4 months, depending on the use of the pool and weather and debris. This business has the best price and delivery is on time. The only one I have used.
