While types of air purifier are various in the marketing, each has its special using way. Especially on the size, which is a troublesome question, what size of air purifier suit me? Will a small air purifier work in a large room? Or can an air purifier be too big for a room? First it is good to think that way, you need to get it on your mind that getting the right size air purifier is important, because it ensures that the unit will work most effectively inside a room.

 

The worst thing you do is to purchase an under-power air purifier for your room, and it does not work well even at cleaning the air around you. While you are unaware of that you are breathing unhealthy air with it running. So you should read this article to know a correct size if air purification in your rooms.

 

 

Will a Large Air Purifier Work in a Small Room?

Yes, absolutely. If you don’t mind some large room air purifiers takes up much space in your room, it’s totally okay to put it there. You might thought it will waste energy for it works for large room. Actually, the tags of ‘large room’ on it only means its highest working limitation. It can work well under the limitation at sizes of the room.

Will a Large Air Purifier Work in a Small Room

 

 

Technically, an air purifier can be too big for a room. But referring to the air purification efficiency, it is accountable. If you use it correctly, it will just perform as well as in a small room. Without unecessary filter replacement cost or energy fee.

 

While if you are only looking for an air purifier for a small bedroom or an office, then it’s better not choosing a device in a maximum of 3,500 square feet. You should focus on the silence working mode more.

 

Because when you are in sleep, or working, a slice of a sound can affect you, a large air machine can’t promise it would not give out sound. And what’s worse, it takes up much room, so it’s not a good choice.

 

So, it makes more sense to get an air purifier for a room size that is properly sized for your application.

 

For example, rooms measures at 150 square feet, then get an air purifier that indicates a square footage rating that is equal to or just above this number.

 

An air purifier with a 200 or 250 square feet rating would be similar in working rate as a unit that measures 150 square feet exactly for that size space.

Can You Use a Small Air Purifier in a Large Room?

It’s better not, you will have to spend much more power in it. To produce same amount of pure air as to a normal size to your room, it takes more time and power. And what’s worse, the air can not be ideally pure as it should be.

 

Can You Use a Small Air Purifier in a Large Room

 

If you are out of saving money to buy an air purifier machine that can only purify a room up to 80 square feet. And that would be a waste of your investment, because it won’t work well at large room air purification.

 

While for people who are really rich, live in a castle-like room, and your each room reaches at 5,000 square feet, then you might not able to find a proper product fits it. That’s when you will need to make a compromise.

 

Instead of purifying your house with one device, it makes more sense to break your home up into small square footage sections and find a device that will work well for each size.

 

For example, if each level measures 1,500 square feet in a 3 level home, try getting an air purifier that is sized to purify 1,500 square feet.
