What To Look For When Choosing An Air Purifier For A Windowless Room
When you are shopping for the best air purifier for your windowless window, you want to construct the following factors:
CADR Rating
The CADR rating is the measure of how much air an air purifier can clean in a certain given time.
A high CADR rating means that the machine can process more air and faster, which is ideal for a windowless room.
Room Size
Windowless rooms come in all shapes and sizes, so it’s important to get an air purifier that’s designed to fit the size of your windowless room.
If you have a large windowless room, one air purifier may not be enough; but if it’s too small for an air purifier, you’ll end up spending money on something that will never meet its full potential.
The best way to find out what works is to measure the square footage of your room and find an air purifier that is designed to cover at least that many square feet.
Noise Level
Windowless rooms can be quite loud, especially if you’re using a fan to help circulate the air. It’s important to find an air purifier with a noise level that you’re comfortable with, so you can run it without feeling like you’re in a tornado.
Filter Type and Replacement Schedule
Windowless rooms typically have more dust in them than other rooms, so it’s important to find an air purifier with a filter type that can handle the extra dirt. Some filters only need to be replaced every six months, while others may need to be replaced every three months.
If you’re going to have someone clean your windowless room for you, it may not matter how often the filter needs replacement; but if you want to do things yourself, then it’s important that you find an air purifier with a filter type that can last at least six months.
Starter Kit
Some air purifiers come with a starter kit that includes extra filters, but it’s important to find an air purifier that you can buy replacement filters for easily.
Many windowless rooms are only cleaned once or twice per year, so if you don’t have easy access to replacements when your filter type has run out, then the machine may become useless to you.
Durability
You want to find an air purifier that is durable enough to last at least a year in your windowless room.
If the machine breaks after only a few months, you’re going to have to go through the hassle of returning it and finding another one.
FAQ About Air Purifiers For Rooms With No Windows
Can you use an air purifier in a closed room?
Yes, you can use an air purifier in a closed room as long as the room is large enough for the machine. If it’s not, then the air purifier will never be able to meet its full potential.
What happens when a room has no ventilation?
When a room is not ventilated, the air becomes stagnant and can start to smell bad. This is because the room is not getting enough oxygen, which can cause you to feel tired and unmotivated.
Are Windowless Rooms Dangerous For Our Health?
While we can’t say they are dangerous for our health, we can say that they are not ideal. This is because windowless rooms can be quite loud and dusty, which can lead to respiratory problems over time.
If you have a windowless room, it’s important to take measures to improve the air quality in the room.
A recent study found that if you have more light exposure through windows it will help you to have more physical activity and longer sleep duration.
