UpStart Components Air Purifier Pre-Filters Compatible with Honeywell 50250 - 50259 Series, 3 Pack

It was the same, exact material as what came with the unit. The best part is that it had perforations so that you could cut it down if need be. We ordered it for my dad's bigger unit, so I ended up getting two for the price of one for my little unit.

These filters are excellent replacements so far for my Honeywell 50250-S (also available for purchase on Wal Mart's website). You do need to cut these filters down to size, but I've decided to save the leftover material to see if I can cut it and use it for my prefilter replacements on my Miele C-! classic suction vacuum! If you're looking for a pre-cut model, do not purchase this, but it you're willing to grab a pair of scissors and cut to size for a more economical choice with good filter results, this is the filter set for you! I would also strongly encourage those with asthma, COPD, allergies, and broncheactasis to purchase both the filter and the air purifier! These really helped my Dad breathe at night and sleep through the night!
