Buying the Best Small Room Air Purifier – Comprehensive Guide

While we have covered all of the details of the best small room air purifiers mentioned up above in this article, some of you might be interested in knowing more. Therefore, we are here with a detailed buying guide related to these compact air purifiers that can be quite handy if you want to know everything about air purifiers in general:

What Qualifies As A Small Room Air Purifier?

The major difference between a standard air purifier and a small one is that compact units are mainly designed for rooms that have a size of 350 square feet or less. Small air purifiers are compact and very handy to use. Due to their compact design, they can be easily moved from one room to another.

Although a small air purifier covers approximately an area of 350 square feet, it does not necessarily mean a decline in performance. It works as good as any large size air purifier in terms of the purification while being ideal for small bedrooms and office spaces. Small air purifiers are not only efficient but also offer most of the features found in larger air purifier units.

Factors to Consider before Buying a Small Air Purifier for Bedroom

1. Maximum Area Coverage

Every air purifier has a maximum area coverage limit that it can serve effectively. Area coverage of any air purifier depends majorly on the size of an air purifier. To cover a large area such as a big hall or any other large space you will require an air purifier that’s designed for large spaces

But for personal spaces like a bedroom, a small air purifier with a coverage of 350 square feet would be more than enough. While some small air purifier units might be rated at 200 square feet, others might have a rating of 300 square feet depending on the model that you buy.

2. Types of Particle Filters

The particle filter is one of the most important things that needs to be considered when buying any kind of air purifier. It is responsible for cleaning most of the particles like dust and allergens from the air. But not all particle filters found in different air purifier units are the same as they have different particle retention ratings.

The quality of particle filters can be very significant for people who suffer from allergies or other breathing problems. Out of all the various options available out there, HEPA-type or HEPA-like filters are fine for most users. However, fine bacteria, viruses, and pathogens are much smaller and need a true HEPA filter or a medical grade filter to be effectively filtered. Both these HEPA based filters can often be cleaned and reused. 

3. Activated Carbon Filters

Other than dust and allergens, you can also find other pollutants like smoke, carbon monoxide, black carbon matter, and more in the air. All of these can be very harmful to the lungs and can lead to serious diseases. Hence, air cleaners have a particle filter to take out solid, suspended particulate from the air along with a carbon based filter to minimize gaseous pollutants, VOCs, smoke, and odour.

In addition to suspended particulate, gaseous pollutants may also be a contributing factor in the unpleasant ambience of your home. An air purifier can get rid of any foul odour while providing you with good air quality with the help of its activated carbon filter. Hence, an activated carbon filter is a must have in any air purifier intended to be used in your home.

4. Recurring Costs

Just like various other home appliances, air purifiers also have a running cost that you have to consider before buying one. However, the cost of an air purifier depends on different models and sizes. While some models need you to frequently replace the filters to keep them functioning, other air purifiers come with washable filters.

Generally, in such cases, their odour filter can be washed and reused that can help the user in keeping it’s running cost in check. As a result, most of you will be able to afford an air purifier since you can simply wash the primary filter and keep using it for a long time. 

5. Warranty

After selecting the right air purifier you would definitely want it to last for a long time. Thankfully, you can easily ensure this by checking the warranty offered by a given air purifier model. As you would expect, different air purifiers come with different warranty periods. Some offer a 1 year long warranty, while others might offer a 3 year which is quite better.

The warranty of an air purifier is quite important to check as it ensures that the unit keeps working for a long time without any issues. Naturally, if you do face any issues later on, those can be either fixed or the whole unit can be replaced under warranty. Other than that, an air purifier with a strong build quality tends to last longer making it a more reliable option to buy.


After going through this article until the end, you must know almost everything about compact air purifiers as we mentioned some of the best small air purifiers for bedrooms in this article. You can also find most of their details like features, specifications, pros and cons, along with various other differences.
