A marketing card was mailed to my parents from “Allergy Relief Center of Nebraska” advertising air filters and vacuum cleaners. They returned the card to find out what it was about. The sales person arranged an in-house high pressure demonstration that lasted for JUST SHY OF 4 HOURS. The vacuum apparently can do everything including forgive your sins (“indulgence” only for the price of $1900.00)… Upon my inspection of the item, I completely reject the product value and would put it in the $160.00 to $200.00 range. The plastic components are not very rigid with exception of the filter container. It looks modern and has a motor that sounds like it operates at very high RPM so I’m sure it has reasonably strong suction, but all Dyson’s have that and their TOP END machine is $599.99. I looked and there is VERY LITTLE product information about this vacuum. The manufacturer site www.filtropur.net/ does NOT have much specification information on the product. Very immature and undeveloped web site… There are NO reviews by Consumer Reports (www.consumerreports.org) They have no review of Filtropur, FSV Inc., HMI Industries, or Health-Mor Inc. So now the product has an obvious design defect. The filter canister DOES NOT seal completely with the air input port on the front. The high pressure sent to the filter from the vacuum motor causes lots of air to escape the defective seal and you will see dirt, dust, and allergens (which they claim are completely removed) accumulate in this area on the vacuum and by deduction back into the air. What good does it do to remove dust and allergens from the carpet and put lot right back into the air where they will be breathed??? If they are going to advertise that it filters out 99.97% of 1 to 2 micron sized particles, how do they account for the % emitted back into the air before getting to the filter? What about refund? The product design alone is enough cause to return it right away!!! I don’t believe there is any vacuum worth $1900.00 after seeing this piece of junk. Thanks for reading this and be super careful not to entertain in-house high pressure sales people.
