The 10 Best Cheap Air Purifiers under $100

We surround ourselves with expensive gadgets and devices for comfortable living but ignore that one thing that surrounds us and is essential for a healthy life. We are talking about air, specifically the purity levels of air within our homes.

Unclean air results in a number of health complications. Difficulty in breathing, allergic reactions, and asthma attacks are prone to occur if the air in our homes is filled with household pollutants, such as pollens, molds, dust, and smoke particles.

Air purifiers restore the freshness of the air to a large extent. Cleaner air also helps us inhale more oxygen into our lungs which, in turn, yields many health benefits and brightens our mood. Inhaling more oxygen keeps us more energetic and strengthens our immune system. These health benefits provide extra fighting power to our body against seasonal and other diseases, such as coughs and colds, or common allergies.

You can confidently opt for any of these air purifiers, but before making a final decision, think about why you need an air purifier. Is it because you need cleaner air to alleviate your allergies? Or is it to get rid of household odors? Perhaps your home is in a dusty area? Or perhaps your bathroom is developing mold?

Any or all of these problems will not be solved if you purchase an air purifier that does not address that specific problem or problems. So, think about your needs and then match those with the solutions offered by the models below.

The AeraMax 100 also has a multi-layered air purification system. Apart from the odor-removing carbon filter, it also has two other filters with advanced purifying technologies. One is the “True HEPA filter,” which comes with the “AeraSafe Antimicrobial Treatment.” The other one is an ionizer, and its specialty is “PlasmaTRUE Technology” for removing air impurities. With a compact size but wide-ranging features, this highly efficient air purifier makes the list of “small but capable” purifiers under $100 that you can definitely consider for your home.

Its filter change indicator will do that work for you.

The first level of air filtration starts with a pre-filter, supported by a True HEPA filter and, finally, a carbon filter.

Considering its size, price, and features, the LV-H132 can be called a useful and smart air purifier.

Its small size has another benefit, though – that of not cluttering small rooms. Despite being in the “budget” category, this air purifier has the added advantage of being energy efficient.

It also functions noiselessly and provides you with fresher air at a fraction of the cost of more expensive air purifiers. When you want to move it with you, you’ll find its 6.5 pounds to be quite convenient.

Buying Guide

There is no dearth of expensive air purifiers, but if you are looking for an economical solution to clear the air in your home, consider buying an efficient model that will cost you $100 or less and still perform well. Of course, that does not mean you look only at the price tag and buy whatever comes in that price range. You should consider some technical specifications before picking up an air purifier to make sure you are getting the best quality in your budget category. Some specs to look for include:

  1. Clean Air Delivery Rate (CADR): As the name indicates, this is the number that indicates the efficiency of that particular air purifier in removing pollutants from the air. Look for a higher CADR number while purchasing any purifier.
  1. Filtration Quality: Check the filtration level rate. The higher, the better.
  1. Area of Coverage: This will give you a fair idea of how much space can be covered by that purifier. Using an air purifier in a room larger than it’s rated for will significantly reduce its effectiveness.
  1. Ozone Production: Some air purifiers take a shortcut to remove odors. They release a higher amount of Ozone to complete the air-cleaning task. But that can have a negative effect on your health. So, do not forget to check the limits of Ozone production in your selected air purifier.
  1. Carbon Filter: This is not the main filter but a secondary one, which acts as a “pre-filter” for the primary filter. This additional feature helps in removing odors and thus keeps your surrounding environment cleaner.

Keep these in mind when you make a decision for the most useful air purifiers under $100. Remember, even the best one can seem to be the worst for you if it does not match your needs.
