Top 5 factors to consider when buying air purifiers

Dust, pollen, smoke, volatile organic compounds, and a variety of unfriendly microorganisms – things that can hardly be seen with the naked eye thought to be found in abundance outdoors, can actually build up indoors. This need of clean indoor air led to the birth of air purifier products, and here are the top five factors when buying one.

Room size

5 factors to consider when buying air purifiers

The first to consider is where you would be putting your air purifier in. Regardless of quality, no tabletop air purifier can cover a 500 square feet room. Likewise, a large air purifier capable of covering hundreds of square feet might be too bulky for a 100 square feet room. Failing to take note here would either mean buying one that is not up to task, or one taking up more space than actually required.

Particle removal

Contrary to popular belief, no air purifier products clean the room of every undesirable particle with the same level of effectiveness. Some are designed to be more effective against pollutants and allergens like dust, pet dander, smoke and odour; while some others are designed to work better against pathogens – bacteria and viruses. One good way to determine what an air purifier cleans and how well it does against what, would be checking out the filter and features like ionizer and UV lamps.

Operating cost

Most air purifiers require part replacements between three months to a year, costing anywhere between a fraction of to more than the appliance’s original purchase price yearly. If you are about buy larger air purifiers, do note that they might have notable electricity consumption, which could go up to half as much as the bill for turning on the air-conditioner. Take this into serious consideration to make sure that a tool for your convenience does not end up becoming a major financial burden.


Most air purifiers require maintenance to function properly, like just about every tool there is. Difficulty of doing such can be anywhere between wiping the exterior to taking it apart and cleaning the insides. One thing to note here is cleaning air purifiers with ionizer feature, which often have collector plates in them requiring cleaning, which unfortunately can break rather easily.


This is often an important, yet overlooked miscellaneous factor. The ionizer feature produces ozone when turned on, albeit significantly lesser than an ozone generator type of air purifier product. To put it simply, ozone can cause a variety of lung problems. While the amount produced by an ionizer is far too few to cause harm, it is nonetheless still something to take note of, especially when someone with lung problems will be within the appliance’s vicinity.
