Title: Needs replacement filters
Review: Nice small little HEPA Filter. Does a fairly good job of removing allergens. I have one in my bedroom, on the lowest setting it is not very noisey - does not interfere with sleeping. My problem with this unit is the replacement filter. I paid $40 for this, but the replacement filters are $30, and need to be replaced every 3 months - $120 per year in filters. I am going to return this machine and buy a permanent filter machine instead.
