how many do you need in a house?

In each room but I must say I don't think they help. I have 6 cats and didn't notice any change in behavior. I used it at my vets recommendation because I had a new male friend and one of my cats started marking everything

I usually keep one and move it around. I have a small house, but it seems to affect my cat in the room it is in and surrounding rooms

2 would be fine. Lots of power here. Back wall pointed out. I have 8 of these and they are THE Best you'll find anywhere. All are over 5 years old. I use them everyday. Not a problem....ever.

Depending on the size of the room, 4 would be plenty! In a smaller room you could get by with 2 easy.

Yes, you need at least 6, but can add another 2. The instructions explain it.

Probably just need 2. We have 1 in a 20×20 patio and it is VERY powerful at full speed.

You can use just 2 in smaller areas. You can use all 4 in a larger area, or use 2 in one area and 2 in another area.

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.

I would venture to guess quite a few. I had 2 and only used a minimal amount .

A shelter in my area houses three but I think two is a better number. Depends on the cat though. My adult male needs to be in there by himself.

Yes, I would recommend 2. We have a neighbor who has a house similar in size and two are adequate for this square footage

My room is quite small and it required two packs so I would say an average room requires at least three. Hope that helps!

Not sure. .I would say two units..one for 1 for upstairs and one for downstairs. .I would call the company. .

I would just buy two just to be safe. That's what I did. My house isn't very big at all but I wanted to make sure I got every inch

Probably a little more over a dozen? Depends on how much of it you use. I layer it on pretty thinly.

I only required one for my 80' of house length. According to materials that came with the unit, more could be added. Sorry I can't give a definite yes.

I'm not sure; I don't use one because my home is so small (only 1400 sq ft).

If you live in an apartment you should have to use to many. I would only put 2 in the kitchen and under the sink. The pest control man said you don't need to use to many only a few where you see the roaches, especially in kitchen.
