Top-Rated Air Purifiers Under $50 Review

Cheap Air Purifiers vs Expensive Ones

Before buying a low-priced unit, make sure that you know about everything that it will and won’t offer you. If you know for sure what features it has, you won’t get dissatisfied with your buy when you bring it home.

The main differences between cheap purifiers and high-priced ones are:

pros maximum space they can handle

pros filtration system type and their efficiency

pros how often filters should be replaced

Maximum Space They Can Handle

Take note that the more the purifier costs the bigger space it can handle. Before getting a cheap unit, realize that it will be useless on large areas, which may be a concern for you if you have a big living or working space.

We came up with the list of the best inexpensive air purifiers that can handle a room that is something between 80-200 square feet in size. If you need a device to install in your bedroom, small kitchen, or bathroom, then one of these units is a good buy for you.

No one has to spend much money on high-priced models that purify rooms of 500 square feet in size. This type of purifiers is popular only with those who live in big houses.


Filtration system type and their efficiency

Another difference between cheap and expensive units is the type of filters they use and their efficiency. Pay careful attention to the filtration system used in the particular purifier especially if you suffer from allergies or asthma. If allergens are not your concern, then you can save some money, opting for a cheaper unit that doesn’t use any high-end filtering technology.

Most cheap air purifiers use HEPA-type filters. Please, don’t mix them with true-HEPA ones. These filters are effective at dealing with particles that are something between two and five microns in size. True-HEPA filters remove 0.3-micron allergy triggers. While units equipped with true-HEPA filters are expensive, a model with an HEPA-type filter is fine for you if you have no allergies.

Note: Our number one pick actually comes with a true-HEPA filter, delivering superior air cleaning results.

How often filters should be replaced

Expensive purifiers come with larger filters that can handle more particles than cheap ones. Most cheap units have small filters. Thus, if you get an affordable air purifier, then be ready to replace its filter frequently. Remember this when choosing the type of an air purifier.
Note: Our pick #3 comes with a filter that doesn’t require replacing, and one can clean vacuum it. Stick to this unit if you want to eliminate extra expenses.
