Danny as been writing about air purifiers for 10+ years. He is a major fan of home technology, which makes him the perfect person to test and evaluate products for HouseFresh

Recent events have caused a major upheaval in our working lives, with many now working from home facing new challenges as a result. Without the office air conditioning they had grown accustomed to, people working remotely have been known to feel sluggish and devoid of motivation while trying to focus on their tasks. 

An air purifier can be the ideal solution to this problem as breathing clean, filtered air significantly improves productivity. However, it’s not always easy to find the right air purifier if you’re on a budget.

Introducing an air purifier into the home can help combat:

  • High levels of pollution
  • Harmful allergens
  • Unpleasant odors
  • Mold and damp spores 
  • Symptoms of asthma 

Paying close attention to the CADR (Clean Air Delivery Rate) of an air purifier will help you determine how much square footage the system can filter per hour. The Blueair Blue Pure 211+ is designed specifically for those large spaces and filters the air approximately every 12 minutes. But the Winix AM80 may be more suitable if you have a medium-sized room and offers a comparable CADR rate at 5 times an hour.

We made sure that all of our choices included True HEPA/H13 filters as these capture the greatest number of particles. We also made sure that each system contained activated carbon to trap unwanted odors such as those from cooking, smoking, and pets. 

To guarantee these air purifiers are the best for your budget, we used consumer report analysis. This meant that we could eliminate any fake reviews and only refer to genuine feedback from people with similar needs to yours and who had actually purchased the units.

FAQs About Air Purifiers Under $300

What do the different filters on an air purifier do?

Air purifiers require different types of filters to perform different functions. You will typically find a HEPA filter installed in an air purifier due to its efficiency. In fact, it is known as a ” High-Efficiency Particulate Air” filter and is involved in trapping air particles like pollen and dust. It can typically capture around 99.97% of particles, which can be as small as 0.3 microns.

You will also notice other filters such as activated carbon, which are used to absorb odors and gases like VOCs.

Another standard filter is a pre-filter, which is considered the first line of defense as it traps larger air particles before they reach the HEPA filter, extending the lifetime of the latter and contributing to better air quality.

Some air purifiers might also utilize ionizers, which work by emitting negative ions that attract positively charged ions in the air. These carry bacteria and other harmful contaminants, which the ionizer filter draws in, neutralizing them in the process.

Is it worth spending $300 on an air purifier?

Aside from your budget, when shopping for an air purifier it is important to consider the effectiveness of the device, since the price relates strongly to its effectiveness. Higher-end models usually have superior components such as strong fans to more efficiently draw in and redistribute the air. Even their filters do a better job at capturing more pollutants.

More affordable air purifiers may still contain quality components, but probably they might not be an adequate solution for handling larger spaces. You may also need to run these air purifiers for longer and at higher speeds if they do not draw in enough air.

Are air purifiers expensive to run?

Purchasing an air purifier does come with costs to keep it working proficiently. You’ll need to maintain it by replacing the filters. Some air purifiers come with permanent filters that only require sporadic cleaning, but you’ll more than likely have filters that need to be changed.

How often this happens depends on the filter as some can last a couple of months while others might keep performing for years before requiring replacement.

Another factor to consider is energy costs. Find out the wattage requirement for any air purifier you are considering, as well as the estimated monthly cost to run it. Those with Energy Star certification will use up far less energy.

Which Air Purifier is Best for You?

Quality air purifiers don’t come cheap. However, you can find a good quality unit without spending more than $300. These purifiers still do an excellent job of purifying the air in any room, and are relatively easy to maintain, so they are worth the money in the long run.
