We live in AZ - SE of Phoenix. Very dusty. Will this help reduce dust in the house? House is about 1950 sq feet. How many units are needed?

This is a great unit for a ROOM - even a fairy large room - but it won't reach around corners to the rest of the place - if you really need a true tpotal house purifier that can be added to you a/c unit. We're n Florida on a lake with a lot of trees and I'm sensitive to the dust/pollen etc. So in heavy allergy season I bring it from room to room, otherwise just use it at night. It does work - when you open it up to clean out the removable filter you'll see how it catches a lot of dust.If you want to know exact sq. footage that it covers, it should say in the description or on their website.

I researched these on line and then selected this model to purchase as a gift. Son was very pleased. You will have to read manufacturer's data to determine sq footage. He is using in a bedroom in a very old house under renovation.

I have three cats and use this in my very large bedroom. It does a good job but only on that one room. Hope this helps.

We are in Virginia. Our unit covers a 15' x 30' room very comfortably. My wife suffers from allergies and she is happy as a pig in manure with this unit. It does have an effect on dust control relative to the rest of the house. However 1950 is a lot of square footage to cover.

I don't know the square footage of the room but it is in the TV room. Not a large room. I have two other larger models and one is in the kitchen (large) and the other in the master bedroom. We live in the desert so there is much dust and we have two dogs. Allergies, yes, but these seem to help and it is amazing what they can pick up when you go to clean them. Hope this has helped you in making a decision.

if possible put the vac outside and connect thru an open window with an extension hose. Otherwise get an add-on fine filter for your vac. The dust can be phenomenal otherwise.

My house is 3,300 and it's is more than enough. I would say "yes" you will be fine. It may take and extra day to humidify, but the end result will be great.

I would assume yes. I just keep it in all the time and bring it out when I want to use it ... Lots of dust here in Arizona :)

The effective cleaning area for this unit is up to 800 Sq ft . As you increase coverage area it will result in slower and less purification of the air of impurities; it may be adequate if trying to address odors if they are from a small area like your kitchen and you willing to trade off the level of particulate purification. If the latter is not an option you should consider units designed for greater than your 1800 Sq ft (specs listed will say "up to") or use multiple smaller units.

It helps some, but this size is meant for a bedroom or other small rooms not a living room. I have mine in my bedroom on my side table (not on the floor) and have noticed some difference in the dust on the furniture.

I'm sure it works best if left in one room and ran all the time. However we have a 3 bedroom with vaulted ceilings in our large kitchen/dining/living room. I run it for a few hours in each room then all night in our living area. We had forest fires 30 mins away from us and the air outside was considered toxic when we bought this. I noticed a huge difference in the air quality in our home. We still use it year round to freshen up the air during the winter and help keep allergies down the rest of the year. Just make sure to clean it often and correctly so the filters work properly.

I believe it does, but I can't quantify it for you! Basically, we see significantly less dust in the room we use it in as compared to before we bought it and in rooms we don't have an air purifier. We live on the cusp of central Texas going to west Texas, which means lots of dust and wind to blow it into the house, so we are very happy with it.

Recommend you use the 3M 2091 Particle Filter which will do the job equally well for dust and save money; both filter types must be replaced when used up.

No, you should get as big a humidifier as reasonably possible. The "whole house" claim is exaggerated. I live in a 1000 square foot condo and the two units I've tried, including this one, struggle to keep the humidity at 35% on a dry day. That's fine for me, but I wouldn't want anything less. Besides, there's no real down side with a humidifier that's more than you need. It will just humidify your space to the desired level quicker and shut off, requiring less frequent fill-ups. The fan is loud on the higher settings, but you can keep it at low. In fact, I wouldn't even bother with this one. I got a slightly smaller Honeywell Quietcare that was quieter and worked more reliably than this one. No, you should get as big a humidifier as reasonably possible.

It's minor. Maybe 1/8". I'm in AZ and in the country and have a LOT of dust. So far nothing in it is dusty unlike the rest of my house.

I have a 2000 sq. ft. house. It does all but the back two bedrooms (about 1700 sq. feet effectively), but that is more of a wall / air flow limitation. I would say about 1500 sq. feet is the ideal for the unit, but you can effectively get up to 2000+ sq. feet depending upon layout / air flow limitations. That is with ozone. I have tried similiar units, and for what it does, this is a great value for the money, regardless of size space.

It will help keep the dust out but not much use in protecting from the fiberglass fumes. Check with 3M

For square footage of room: http://www.honeywellstore.com/store/products/honeywell-17000-s-quietcare-permanent-true-hepa-air-purifier-germ-reduction.htm.You have to buy the coarse prefilter every few months, depending on your environment. It's cheap.

I have used it in a very dusty and ash filled area under extreme conditions. the room I use it in is 20' x 8' x 8'. I actually go through a set of filters every 2 months. definitely worth it though.

I'd say so! I live in Seattle where we have a lot of dust due to being in a Volcano region. I'm very happy with it. Great product!
