Choosing a Quality Air Purifier Under $100

Type of Pollutant to Remove

What sort of area do you live in? Many homes and regions can have air that is filled with:

And more! Getting an air purifier can prevent these contaminants from getting into your system.

Filter Type & Life

There are a variety of filter types that can be included in an air purifier, sometimes at the same time. Conventional air purifier filters are HEPA filters (High-Efficiency Particulate Air), carbon, prefilters, ionizers, ozone (banned in many areas), and UV filters.

These filters often last between three months and a year, depending on the type of filter and air quality in your home. With these filters, some great features to look out for include removable, washable, permanent, or antimicrobial.

Particle Removal Capacity

Air purifiers are often judged by their CADR, or Clean Air Delivery Rate, which is how often the air in a room is replaced or cleaned. Pick up a model with a CADR of 350 or more and a true HEPA filter for the best air quality.

Room Size vs. Coverage Area

Knowing what size room or area you want to cover is essential to getting the right air purifier for you. Smaller rooms are typically better suited to cheaper smaller models, but you can find some very powerful air purifiers.

Energy Efficiency & Maintenance Cost

Finding a model that is energy efficient and has low maintenance costs is essential. Often air purifiers have timer functions or sleep settings to help ease energy consumption. In terms of maintenance, read the product description and customer reviews to see how regularly you should change the filters and how much that would cost for maximum cost efficiency.

Other Considerations

  • Noise Level
    No-one wants a noisy machine keeping them awake at night; find a model with a dB level of 50 or less.
  • Aesthetics & Placement
    Having an ugly machine on the coffee table is not ideal; find a sleek and compact model and place it on a desk or shelf for best results.
  • Safe & Easy to Use
    Find an air purifier that has safety features such as a child lock and easy to change filters.
  • Manufacturer Reputation
    Once you have some potential candidates, do your research into the manufacturer by looking online and reading customer reviews to ensure that they are trustworthy.
  • Warranty
    Air purifier warranties typically last anywhere from one to five years.

Cheap Vs. Expensive Air Purifiers Compared

While cheap air purifiers can save money in the short term, poor quality models can cost you more in terms of repairs and replacements. More expensive models are built with higher quality materials; they are often more durable and effective than cheaper counterparts. However, it is possible to find a powerful and efficient model for a reasonable price.

We recommend that models under dollars are used for small spaces such as bedrooms, attics, smaller basements etc. Areas such as these generally have lower square footage and therefore the air purification needs are lower.
