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 BAP9240 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 BAP9240 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 those large particles before they reach the main Hepa filter and as a result can extend the life of the Hepa 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.
These are a fab addition to bap9240 you have lots of spares when washing others top quality just like the company would not be without them
After research I learnt it is not a hepa filter but a carbon filter that draws the vapour from Vaping. I got these carbon filter pads because I was fogging out my living room. 2years worth for the price is a good buy :)
This is the only website to sell filters for my Bionaire machine. So worth it as you can change filters wash without losing any filtering time. Great buy and price.
Actually bought for a purifier, but I have also used one in my PC to help filter out the dust intake :)
