Note: Boair Flexible Filters are very thin, at around 1/4 of an inch in thickness. Due to their flexibility they can also be safely bent.

2. How did you get your filter measurements?
If you're replacing a disposable filter, you'll find that your existing filter is probably smaller than the measurements printed on the side of it. For example, a filter marked 20 x 20 x 1 inches is usually only 19 5/8 x 19 5/8 x 7/8 inches (i.e. the major dimensions are 3/8 of an inch smaller than what's printed on the filter, and the thickness is 1/8 to 1/4 of an inch thinner).
For your convenience we provide 3 ways for you to specify how you arrived at your above measurements - please choose carefully:
These are the measurements that are printed on the side of my existing disposable filter, so make my new filter 3/8 of an inch smaller on each of the major dimensions.
I took exact measurements of my existing filter with a measuring tape, and I would like you to make my new filter EXACTLY the size I entered above.
I measured the opening that my filter slides into, so make my new filter 3/8 of an inch smaller on each of the major dimensions, to give me a little room (3/16 of an inch) on each side.

3. Would you like to order a second "same-size" filter at $20.00 off the already low price?
Some customers order a second filter so that when their first filter needs cleaning they can replace it with a clean filter immediately without having to clean the first filter right then and there. This is only for convenience and is not a necessity.
No thanks, I only want one filter of this size.
Yes, I'd like a second "same-size" filter at $20.00 off the already low price.
I need more than 2 same size filters and would like to take advantage of the $20 off each additional "same size" filter discount on all additional same size filters after the first filter. The TOTAL number of filters I need is :
