A: The writing side of the filter should be facing out at all times. Yes, you should see Biosponge, as this is the side the air should hit first.

Q: What is the size of the bio sponge filter and how many are in a packet?

Asked by: jerry - 11/4/2015
A: Have your A/C tech measure for you. You also need to have a margin around the edges (in fractions of inches) so that the correct size filter fits within the frame that your order in your first purchase order. I keep the sizes for future replacements inside my small personal phone directory. There are 6 filters inside each purchase.

Q: Last year I purchased these filters and the price for 6 was $ 41.00? now they are 6 for $ 58?? Do you offer any coupons for this purchase? I am a single mom with an adult child I am caring for and this is quite a price increase. Is there anything you can do to help me on the price? I am a senior citizen, if there are any discounts available.

Asked by: Susan France - 11/5/2018
A: Your price for the previous year was for the frame and filters. When you order the new set up, we give a break on the filter pads so it a good value to start with.
