Things you should consider before buying

  1. Operating costs

    As is the case with any other electronic equipment, there is a cost to using an air purifier. Most models have an annual operating costs of $150 to $200 for filter replacement and electricity charges (with the majority of that cost being for filters). Filter prices can range from around $10 each going up to well into the hundreds. Some units use a pre-filter to capture large airborne particles before they reach the HEPA filter which extend their life. Depending on your use case, you have to change the carbon filters every 3-4 months and the main filter at least once a year.

  2. Quietness

    If the noise level of the air purifier you purchase is not under control, it will soon become annoying and distracting especially if you work or sleep with it running. It is better to purchase a bigger purifier and running it on a lower speed rather than purchasing a smaller one and cranking it up to the max.

  3. Room size

    Sounds pretty straightforward but most people overlook this when they are making their air purifier purchase. Some purifiers are designed to work best for smaller rooms while others are designed keeping bigger rooms in mind. While the latter can very well work for the former use case but the reverse is often not true.

Conclusion

When choosing an air purifier, first consider your indoor air quality needs. If you have allergies, you should choose an air purifier which was designed keeping that in mind. HEPA air purifiers are good enough for most cases, but you can look for UV-C and/or activated charcoal filters as well on top of that. If you suffer from asthma or if your symptoms are triggered by odor and chemical pollutants, you’ll want to consider a purifier which removes those from the air. If you consider all that has been mentioned in this article, you will definitely find the product you are looking for.
