Product review (2 stars): Different constuction as original filter
This filter replacement fit the air cleaner unit with substantial gaps. The quality of this filter is a cheap imitation of the original filter that performs at approximately 35-45% of the factory filter. It is constructed with a thin cardboard-like casing that does not seal for an airtight fit. The edges leave a large enough gap between the filter and slot on the unit that for the 1st time of the unit's life, there is a moderate amount of buildup on the inside of the unit. The unit is used in a 12x16 family room and since the filter quality is so low, the unit no longer performs as it did before changing to this filter. The casing of the original filter is a hard plastic, not a paper casing like this replacement. The actual filtering part of the replacement, one side is a netted plastic which does not trap air particles, and the other side is a thin hepa type filter, if that is what they classify it as, has little effect on air cleaning. Please note that at the cost of this disposable filter, (the 1st one fell apart when it was cleaned) makes it a costly 1 time use filter. I am glad I saved my old filter because it works a good 80% better. I will be using it instead of this 2 pack.
I have pleural fibrosis & asthma and for my condition (which is not in the moderate stage yet), this is an insufficient replacement for cleaning the air. The only reason I did not give a 1 star rating is because it did trap a minute amount of dust.
