VornadoReplacement AQS500 Air Purifier Filters (2-Pack), multi/none

I wrote to Vornado to ask how many microns their filters capture in the AQS 500 model. I hope this helps someone else. This information is for this # MD1-0015 (pack of 2) OR # MD1-0014 (same filters, but sold as a bulk pack of 4 filters).Their consumer care said: "The MD1-0014 is rated MERV 11. MERV 11 captures particles between 0.3 and 10 microns."

I chose this air filter machine because of the reviews. God bless you all! When I had carpets for over seven years it was hard for my kids and my husband to breathe and sleep well through the night. I'd vacuum every two or three days the last three years. Then we decided to change the floor to wood. Now I see clearly how much dang dust gets into a place. My God. I sweep and mop every day at least two rooms. I bought this machine before changing over and it helped. Now six months later, including 2months ago of wooden floors, I see the build up and I'm purchasing the replacement filters tonight! It's gray and white and some saw dust from the cutting of the wood. Thank God I had this thing on all the while. I put it on high every night. We like the consistent sound. It puts us to sleep. We live in the city so even at night we will hear occasional buses and motorbikes. It works well on the lowest setting too. I believe, buy it right from the get go and it will last if I take good care of it. I'm glad I bought it at the right time.

Whelp. After a *decade* of my trusty AQS500 cleaning air 24/7 like a boss, the bearings are finally shot.I really want to buy another, but Vornado don't make them anymore and they don't exist online anymore at any store.I might try and replace the bearings.. but this might be my last filter replacement.Goodnight sweet price.

the replacement filter seems a good price because it took about 1 year before the replacement light went on.

Very handy item.

Use for our air cleaner.

I ordered these through Amazon to spare myself having to go to a Bed, Bath and Beyond to purchase replacement filters. This was a convenient and affordable alternative. I use this device in the room where I keep my cat's litter box. I have it running on low at all times and bump it up to high whenever I am scooping out the litter clumps. These filters in this device are very effective at extracting all the particulate matter from the air that is stirred up during the box cleaning process. I can confidently recommend to others.

Great product

Fits my Vornado unit perfectly.
