Lots of air cleansers are proficient at filtering contaminant particles out of the air (dust, smoke, pollen, and so on), however they are not necessarily excellent at eliminating gaseous toxins like VOCs or radon from the air that might accumulate from adhesives, paints, or cleaning products. Allergens that are embedded into furnishings or floor covering are likewise not captured by them.

Furthermore, the efficiency of air cleansers in real-world scenarios most likely will not mimic those of regulated conditions in a lab (what those “99% efficiency” claims are describing!). The area, setup, flow rate, and for how long it is running for will all vary, as will the conditions in the space.

True HEPA. True HEPA filters are effective at eliminating ultra fine particles (think: dust, dander, pollen, mold and other typical allergens in the house). The market requirement for such is that the system must have the ability to remove a minimum of 99.97% of particulates measuring 0.3 micron diameter in a laboratory setting. Keep in mind, it is necessary to note that in real life settings, the real effectiveness of these devices would be far less as brand-new toxins are continuously emerging. Note that there is no industry standard for the terms “HEPA-like” or “HEPA-type,” and are mainly utilized as marketing tactics to get customers to purchase the product.
