How can an air purifier improve your life quality?

If you find yourself coughing a lot, have irritated sinuses, or even find it hard to catch your breath, then your air quality might be suffering. Air purifiers help to remove unwanted particles from the air, allowing us to breathe easier. In fact, you might not even be aware of how bad your air quality is, until you try an air purifier in your home.

Many users of air purifiers were shocked to discover how much fresher the air in their home was, after they started using the product. Sometimes you just don’t realize what can improve in your home, until you make a change.

Features to consider while choosing a small air purifier

To help you purchase your next small air purifier, here is a list of important features to consider.

Type of filters

There are many types of filters for air purifiers and the important thing to remember is that you need to buy specific replacements for each different model. Typically speaking, filters need to be changed at least once a month. If you live in a smokier environment or have a few pets in the home, then you might want to change the filter every six months.

Most filters use HEPA technology which traps air pollutants such as pollen, mold, dust, and pet hair. Some filters, like with the Hamilton Beach 04384, are permanent and don’t need to be replaced. You can clean the filter and then reinsert it back into the machine. This can save quite a lot of money each year.

Fan speeds

Air purifiers rely on a fan to distribute the clean, filtered air into your room. The larger the fan speed, the quicker the air is circulated. Almost of the products on our list, including the GermGuardian AC4100 and the Blue Pure 411 have three fan speeds. Having different fan speeds allows you more control over your air purifier.

Fan speed also impacts noise levels. For those that want a quieter air purifier, you will want to keep your machine on the lowest fan setting.

CADR level

CADR stands for Clean Air Delivery Rate. It is measured in cubic feet per minute and refers to how much air has been filtered over one minute of time. The higher the CADR level, the more powerful the air purifier is.

If you and your family have allergies or any sort of breathing issues, you will want to invest in an air purifier with a higher CADR level, so that you can rest assure the air is cleaned quickly, and your health will not be impacted by what you breathe in.

Coverage area

The coverage area of an air purifier basically means how large of a room the machine will function well in, or in some cases, if you are looking for an air purifier for a car, how large your car is. If the area is too large, then the clean air will continually be mixed with unfiltered air, negating the effects of an air purifier. Coverage area is a significant specification to consider with your purchase.

If you just need an air purifier for a bedroom, all the items on our list will work fine. If, however, you have an apartment or even an open-concept living area, then you will need an air purifier with a large coverage area.

Noise level

The amount of noise that a small air purifier gives is vital to take into consideration. For those that are more noise sensitive, and like an ultra-quiet home, find an air purifier that is whisper-quiet; otherwise, you could start to become irritated by the loud sound very soon. It’s also a good idea to think about if you will be running your air purifier at night. While some people like a bit of white noise when they fall asleep, others need absolute quiet. Most air purifiers will run between 17 and 50 decibels.

If you are worried about the noise level, look for a small air purifier that has multiple fan settings. The lower the setting, the less noise your air purifier will make. So, you can run the machine on a low speed at night for quiet, and a high setting during the day when noise isn’t so important.


Best Small Air Purifier

While all of the air purifiers on our list fall into the category of small appliances, each will vary. The TRUSTECH 3-in-1 Air Purifier is the most compact on our list, measuring 6.7 x 6.7 x 7.5 inches, but even being such a small unit it one of the best air purifiers for mold. Conversely, the LEVOIT LV-H132 is the largest and measures at 32 x 19 x 19 inches. Before you purchase an air purifier, think about where in your home you want to place it. Then, measure that space. There’s nothing worse than buying a new air purifier, only to discover that it doesn’t fit in the spot you planned for. But if you want to check other models as well, it is highly advisable to take a look at Therapure air purifiers, which also offer different smaller units.


The standard warranty for an air purifier is between one and two years. This is adequate and you probably don’t need to consider an extended guarantee on any product. If any issues should arise, be sure to contact the manufacturer as soon as possible. Sometimes it can take a while to resolve an issue, and if you’re nearing the end of your warranty, you will want to make sure a new part of the product is shipped to you before the coverage runs out.

Extra features

Small air purifiers vary in type. Some are basic, budget-friendly options, while others come with more high-end features.

A remote control is a nice option, as it allows you to change settings without having to always get up. A timer allows you to set your air purifier, which is perfect if you are worried about your electricity bill. There are also some models that have light features. The LEVOIT LV-H132, for example, has a night light function. There are two brightness settings and it emits a calming sound that can help create a sense of comfort for any child, or adult.

Tips to maintain your air purifier

Best Small Air Purifier

You want your air purifier to last a long time, and keep working well. To begin with, place your air purifier somewhere that it has a lot of space. You don’t want anything to touch its sides. This impacts that air flow and can also make it heat up faster, pushing the internal motor harder than it should be.

The windows and doors of your home should be closed, so as to prevent unwanted air particles to enter the home. Too much dust and pollen, and no air purifier will be able to combat it. If you are using an air purifier in a bedroom, try to keep that door closed as much as possible, too. If an air purifier can only work in a small setting, then having the door open will create too much air space for it to filter.

Finally, the best way to maintain your air purifier is to change its filters regularly. This can start to be a bit costly, but there’s no point in having an air purifier if its filters are clogged and can’t work properly. You should clean or replace your filter at least once a year. Some air purifiers, like the TRUSTECH 3-in-1 Air Purifier, will have a light indicator to remind you. If not, pick a date that you won’t forget, such as the start of spring, for spring cleaning.
