Buying Guide: Tips to Buy an Air Purifier

If you think air purifiers are on the list of luxury items, you should think again. Nowadays, they have become a necessity as the air is full of different types of unhealthy stuff, such as bacteria, pollen, dust and dander, just to name a few. If you are looking to buy one, we suggest that you remember the tips given below.

Get the Right Fit

First of all, the product should be small enough to fit in the space you have in your room. For instance, if you want to place it on a table near your bed, make sure the table has enough space to hold it.

Since air purifiers clean the environment around them, make sure you place them in the room you spend most of your time in. For instance, if you spend most of your time in your living room, don’t place it in the bedroom and vice versa.

Make sure you leave enough space on both sides of the unit otherwise, the unit won’t work. For instance, if you place furniture near the unit, it will block the vents the unit pulls the air through. In some units, the vents are located at the back. Therefore, you may not want to place the device against the wall.

HEPA Filters

If possible, you may want to get an air purifier that features HEPA filters. HEPA is short for high-efficiency particulate arrestance. Actually, the unit contains thick filters that can trap a lot of airborne particles that may have a negative impact on your health.

Some units also have extra filters like pre-filters. They can trap big dust particles in order to capture big allergens. The activated carbon filters are powerful enough to do a great job.

The thing is that the quality of filters is of paramount importance when it comes to buying air purifiers. Although it’s not possible to get an idea of how efficient the unit is unless you give it a go, make sure the filters are thick enough and the material they are made from is high quality. Now, if you feel that the filter is flimsy, make sure you don’t use it.


If you can get a unit that comes with a pre-filter, you should go for it. The reason is that pre-filters can help trap large dust particles. This will have a positive impact on the life of carbon and HEPA filters. They work by preventing dust particles from accumulating in the filter.

The good thing about pre-filters is that they are easy to wash. On the other hand, HEPA filters are not washable, and they just need to be replaced. Based on the model and brand, the replacement cost may vary.

The life of the filter also varies based on the pollution in your home. Generally, HEPA filters with no pre-filters can lasts up to 6 months. On the other hand, units that have pre-filters in them can last up to 15 months.

So, these are a few things to keep in mind when buying air purifiers.
