allergy relief center bought a air purifier, now can' find the company to get replacement filters. $1900.00 unit is no good. millard Nebraska

A door-to-door salesman that said he was with the Allergy Relief Center of Omaha showed my husband and I, 3 products that could improve the quality of the air that we breath in our home. Since we both suffer from allergies we wanted to see what he had to offer. The first was a vaccum, the second an air purifier, and the third a filter for our furnace.  

We only purchased the air purfier and filter for the furnace, that was a year and a half ago. The filter is getting dirty and needs to be changed, but we can not seem to locate the company to get a replacement filter for the air purifier, so our $1900.00 air purifier is worthless without being able to replace the filter.
