When it comes to air purifiers, the mid-priced models are the most popular and offer the best overall value. However, if you need to purify a small room or space, cheaper air purifiers are usually more than enough. For larger rooms, it is always better to invest in a more expensive air purifier. The Clean Air Delivery Rate (CADR) is an industry standard rating that describes the air cleaning effectiveness of an air purifier for particles from 0.10 to 11 microns in size.
It is based on laboratory testing and the volume of air moving while cleaning. The Winix 5500-2 is a direct competitor to the Coway AP-1512HH Mighty, having a nearly identical CADR and offering 5.1 air changes per hour (ACH) in a 350 square foot space. HEPA air purifiers use fans to blow clean air out of the device, so fans are important components here. In its Boost configuration, when it was moving the maximum amount of air, the air could reduce 0.3 micron particles by 61.3% under ambient starting conditions and 57.0% under clean starting conditions.
Pure Enrichment's PureZone portable air purifier can help improve your car's air quality, helping to eliminate 99.97% of dust, pollen, pet dander, smoke and odors. This air purifier has a HEPA H13 filter that captures 99.97% of contaminants as small as 0.3 microns, and it has a built-in air quality sensor, so you can put it in automatic mode and it will activate as needed. In addition, Cabiclean and Durabasics filters fit perfectly into the machine, hermetically sealing their edges to prevent unfiltered air from escaping another important factor in HEPA performance. This prevents air from bypassing the filter around the edges and ensures that virtually all of the air drawn through the machine leaks HEPA, a design that is likely to contribute to the Mighty's excellent performance. Most people don't need an expensive air purifier; it's great to have one if you have special needs or want the best that money can buy, but it's not necessary. Air purifiers will remove dust and other particles from the air, but they will not remove dust or dirt from surfaces. When choosing an air purifier, it is important to consider the size of the room in which you plan to use it.
For smaller rooms, there is no need to purchase an expensive unit that covers more than 500 square feet. However, for large rooms and sometimes even medium-sized rooms, it is always better to carry a more expensive air purifier. In conclusion, cheap air purifiers are worth it if you need an air purifier for a small bedroom, office or small living room. However, for larger rooms it is always better to invest in a more expensive model.
