Best Air Purifiers Under $100 Dollars

Low Budget Air Purifier

Cleaning indoor air of toxins and allergens can be expensive. An air purifier under $100 won’t be able to offer much help if you have a large home with big open rooms. In that situation, there really is no other choice than to buy a big air cleaner that can cost hundreds of dollars. Smaller ones won’t be able to filter the amount of air circulating in a large room.

Thankfully for those of you looking for a budget air purifier, there are cheaper air filters available that are more than able to clean smaller rooms and personal spaces to the highest degree.

Budget air purifiers are typically made for small to medium sized rooms or just to purifier your immediate personal space. Meaning you can place it on the end of your desk, blowing directly at you. This method is especially useful if you tend to sit in the same place for long durations – like when you’re at work.

From all of the air purifiers under 100 dollars, these were by far the best on the market in 2019:

What To Look For In A Budget Air Purifier

When you want to save money on an air purifier, you need to pay close attention to details. It’s very possible to find an excellent option at a reasonable price as long as you are ready to spend sufficient time on the research.

Consider these things when looking for budget air cleaners

HEPA Filter – Here is one feature you may not want to avoid when choosing an air purifier. This filter takes care of 99.97% of harmful particles 0.3 microns in diameter. If the air purifier is equipped with such a filter, it’s bound to do an excellent job cleaning your space.

Fewer Smart OptionsSmart options are nice but you can do just fine without them. More often than not, the high price of an air purifier stems from the number of such options. A budget model can clean your air without them. Such options are air quality sensor, filter replacement indicator, Wi-Fi operation, timer, and the like.

Budget Replacement Filters – When looking for a cheap air purifier, it’s highly important to check the price of replacement filters. In some cases, the yearly maintenance may not be much cheaper than the purifier itself. Look for purifiers that have as many washable filters as possible.

Long Warranty – A low cost air cleaner may not be made from the highest quality materials. If a manufacturer is ready to offer a long warranty then the quality of the air purifier is likely to be high.

Coverage Area – Always check the recommended coverage area. In many cases, a low-budget air purifier can only work in small rooms.

Filtration System

Even though this air purifier is very small, it still has a powerful filtration system:

Washable pre-filter – captures large contaminants in order to keep them from straining other filters.

True HEPA filter – removes 99.97% of pollutants 0.3 microns in diameter. It deals with pollen, pet dander, dust mites, and numerous other allergens. The filter needs to be replaced every 9 to 12 months, depending on the operation frequency. The replacement filter costs about $10.

5. Hamilton Beach 04383A Air Purifier

Hamilton Beach 04383A Air Purifier

This small air purifier can service rooms up to 160 square meters (as the manufacturer claims). It comes with a permanent HEPA-grade filter, which means you don’t need to spend money on replacement filters. This unit has a sleek design and works quietly.

Filtration System

The filtration system of this air purifier differs from what we’ve reviewed above. It comes with a permanent HEPA-grade filter. This filter is highly advantageous for users with a low budget since it doesn’t need to be replaced. All you have to do is vacuum it on a regular basis.

However, unlike True HEPA filters, this one only captures pollutants 3 microns in diameter (vs 0.3 microns for True HEPA filters). It means that this air purifier can’t deal with small particles. Accordingly, it may not be a good choice for people with severe allergies and respiratory problems.

The total annual maintenance cost is $0.

Smart Options

This air purifier doesn’t have any smart options, which seems fair when you consider its low price. It has three fan settings, the lowest one of which produces almost no noise, making it a great choice for the bedroom.

Since this air purifier isn’t AHAM certified, it doesn’t have a CADR rating so it’s hard to estimate the size of a room it can actually service. Most likely, it doesn’t exceed 100 sq. feet.

Pros:

  • Low price
  • No annual maintenance expenses
  • Quiet operation
  • Compact design

Cons:

  • HEPA-grade filter instead of True HEPA filter
