I’ve been running the older version of this air purifier 24 X 7 for over 10 years…maybe 12. It is backed up against a wall in a vaulted-ceiling room between a piano and organ where cats like to play. It takes up very little space and consumes a great deal of dust and hair. The exhaust blows straight up the wall which is perfect for this location. Recently, it began emitting a high-pitch, undulating squeal. I assumed that the sealed bearing on the motor shaft was wearing out. So, I ordered this new Hunter Air Purifier. In the mean time, I placed the old squeaky cleaner on its back and soaked the motor shaft with CRC Heavy Duty silicone spray while turning the shaft with my hand for 5 minutes. That was a month ago and it is still running as smoothly and quietly as new. The new cleaner is still in the box, however, I did test it to make certain that it was in good working order.

How would you like to save a ton of money?

Just like printer companies sell their printers at a bargain and then charge a fortune for the ink cartridges, air-cleaner manufacturers employ the same tactics with their disposable filters. Check their prices. OUCH! $30.00 to $60.00. For years I’ve been using the same pleated, high-efficiency filters that I use in our central heat and air system. I buy them by the case lot(12), online from ACE Hardware for $4.00 each (free shipping to store) and cut them to fit the Hunter Air Purifier. ACE runs frequent sales.

Now, how about the expensive charcoal-pre-filter? Check out the universal replacement pre-filter 38002. They cost about $10.00 each. I have found them in bulk for as low as $8.00 apiece. Cut them to fit. Even the leftover pieces can be easily connected with the enclosed male strips of the hook & loop (Velcro).

Of all the air cleaners running in our home, this Hunter is the least expensive to run 24 X 7 because I can make alternative filters. This is not the case with the large barrel-shaped cleaners and filters that circulate air 360 degrees. When the barrel-shaped air cleaners die, I replace them with these Hunter wall-huggers.

When my back is against the wall, I don’t go to the mall. I look for a bargain. That usually begins with Amazon.Com.

I cannot believe what a great job this air purifier does. It is so quite that you forget that it is there. I have asthma and purchased this hoping it would help. At first I thought that it was not working but gradually I started feeling better and the dust (I live in a leaky old house)has gradually dissapeared from the living area. The only drawback is having to clean the filters often but that is easier than dusting ceilings!
