Maintaining optimum efficiency and prolonging the life of your air purifier.
These pre-filters are designed for use in both the Lifetime Hepa Filter and Smokestop versions of the Bionaire BAP1700 air purifiers. Using a pre-filter protects and prolongs the life of the air purifier by trapping all the larger dirt and dust particles before they enter the workings of the machine and the all important Hepa filter stage.
Prolonging the life of the Hepa Filter
The Hepa filters inside the BAP1700 are designed to trap ultra fine particles such as allergens, dust mites, pollens, spores and pet allergens (dander) . These tiny invisible particles are so small that the Hepa filter can hold millions and millions of them at a time. However, if the much larger dust particles (such as those visible in a shaft of sunlight) are allowed to find their way into the hepa filter they very quickly take up all the available space clogging it up prematurely and forcing early replacement. These pre-filters trap all the large particles before they reach the Hepa filter, therefore prolonging the life of the main filter by up to 100%.
Two Year Supply
We recommend replacing the pre-filter once every six months to maintain your purifiers performance. This pack contains 4 filters and therefore enough to last for a full two years.
