Last Updated on April 5, 2024

Without question, air purifiers are the most effective machines to get all the toxicity, smoke, dust, and odor out of the room and leave fresh air to make a good environment. But a common question that arises among users is, “how many air purifiers do I need, depending on the size of the area?”

Well, there is no specific number to this, really. The number of devices may be one or more. It mainly depends on the room’s shape and the overall device’s capacity.

You also need to consider many other factors, especially when determining the number of air purifiers you need. Want to know more? Binge on till the very end of the article.

How Many Air Purifiers Do I Actually Need?

The amount of air purifiers you need depends on the measurements of your apartment. A single air purifier is not enough if you have a large house. You would at least require one purifier for each of the rooms of your home.

However, if it’s too much for you, then you can also get a portable air purifier for cleaning the air especially when you’re sleeping or planning to spend more time there.

You can also have a large purifier with a good capacity so that it can easily cover two or more spaces in your home. Well, not just the size of the room, but if you have too many people under one roof, in that case, the purifier numbers can vary.

Note: An air purifier takes around 30 minutes to 2 hours to clean the air of the entire room.

How to Choose the Right Air Purifier for Your Home?

So, here in this section, we’ll let you know all the ins and outs of the ways you can actually make your pick for the right air purifier size. Therefore, don’t skip any of the following points to know them all!

Know Your Budget

Without question, before you go on choosing an air purifier, the budget is a must. There are hundreds of different products that you can pick or choose from, but before any of that, you need to ensure the quality and your budget are on the same page.

This is because there’s no point in looking for quality if it tightens your pocket. So, always know your budget before you go on to pick a purifier for your space.


Knowing the space of your rooms is essential. As mentioned before, the size and number of your air purifier depend a lot on the overall space of your home. So, before picking any air purifiers, you should always know the size of your area and the number of members staying there.

The Quality of the Purifier

Purifier quality is a must! Now, a misconception among many new users is that “high-quality air purifiers are super expensive.” Well, the statement is not entirely correct.

Yes, best-quality purifiers can cost you some extra cash, but it’s not going to extend your pockets too much. So, always check the overall quality before you confirm your order. We even recommend you take the seller’s help and get all the queries answered before finalizing.

Note: There are more things that are important to consider, like the perfect temperature for using an air purifier, changing filters, and more. So, ensure you look over these factors too!
