What size room or house does one unit cover? How often do you replace it?

We bought two of these Bell & Howell Electromagnetic devices, and returned both. They were defective and didn't work. My mother had one of a different brand that worked really well for a long time. Silly me threw it away without remembering the brand.

I am using it in my garage, about 30 by 40. I have been using it for about 2 months and it seems to be working .I have no seen spiders or bugs with it in use.

It covers an entire floor as I used it In my basement. The water bugs would just roll over. It kept the mice out as well.

I have one in my shop that is 1000 square ft. and I have one at home in a three bedroom double wide mobile that has been in use for around 5 to 6 years now. I used to have mice and droppings all over in my shop, now I have seen probably a half dozen droppings in the last 9 months. The house has had one in it since I moved in and I have never had any mice problems. Hope that helps.

I was told by my doctor that I should replace it at least once a year not only due to possible bacteria but the plate on the bottom connects to the heater plate in your machine and it can cause the one in your machine to burn up (own experience) also your insurance company should provide 1 free per year but I keep extras just in case. These are better than the ones I get from the supply company!

Hello I do know that the manufacturer says every six months but I do think it is all according to the situation you're in I have two of these units in my place and if I do not change every month there is a big problem.Thank you so much for your informationJohn P. S. You did ask me my opinion that is my opinion.

Depends on the size of area. I would say 8x10 ft room then 1 is good. Bigger then that get 2

I was running the air purifier 24/7 days a week for 5 months during our winter, and by the 6th month I had to replace it. not to say that is what may happen to you, but something to consider if your planning on running it that way. I needed to run it all the time since my allergies are worse during the winter. it also depends where are how much dust is pucked up in thearea where you place it.

At the beginning of each heating season. If you have a long heating season and/or very hard water, probably replace twice per season.

It depends on how often you run the unit and how much dust/allergens it's filtering out of the air. If it is always running then generally the filter should be replaced every 6-8 months.

I have a 2000 sq ft home and don't use the forced air much, maybe 1 hour or so a day. I change mine every 3-4 months. Please see the answer from the filter salesman in reviews.

We had one in a 12 x 10 room, I believe that was a little big for it. But we had it near our dog's bed in the den and it kept all smells down from that. The other one we used in a 12 x 12 office at our shop and I feel it did an excellent job. So I would order what I could to plug in near trouble areas such as kitchen or bedroom or wherever you have odors that are ongoing or off and on. Change out the filters regularly and/or just wash them out. I ordered extra because we have a Labrador. So the dander and hair does get filtered and needs to be cleaned out. I was pleasantly surprised by how well they work. But they are not designed for that large an area using just one. I would have to look again but I believe the instructions says an area around 10 x 10 but would need to confirm that.

when using mine in room about 450 sq. ft. it goes to about 50% with 1 re-fill daily

Follow manufacturer's directions. I live in a 1600 SF, 2 bedroom, 2 bath house. I bought three units because they were offering a package deal (otherwise I would have purchased only one for the master BR), and put one in master BR, one in second BR, and one in living area. Putting one where you sleep is most critical, especially if you have gas heat (we do).

I use two of them to cover my 4800 square foot house. Seems to do the job. I put one in my bedroom and the other in the Family Room so they are most effective where I spend most of my time. Helps a lot to reduce pollen to a level where I have no allergy symptoms when inside.

You don't need two units. We have three furnaces and installed on the most central. The moisture spreads through the house.

The whole unit has to be replaced. I have found out if you clean the unit with baking soda and vinegar daily, you can replace it within 5-6 weeks.

I have two units. In high traffic area near my kitchen, it was about a 9 months, so I got the larger 5500 unit for here. In my bedroom, it has been about 18 months, and it is still good.

We change ours once a year. Not sure if that is what is recommended though...
