Can air purifiers be harmful?

Specific effects may include throat irritation, cough, chest pain and shortness of breath, as well as an increased risk of respiratory infections. Some ozone air purifiers are made with an ion generator, sometimes called an ionizer, in the same unit. Experts agree that ozone is harmful to health. Certain regulatory bodies have taken action on this issue and air purifiers that generate ozone are banned in some places.

Certainly, these products generate significant amounts of ozone that, if inhaled, can cause long-term damage to olfactory cells and lungs. Even more worrying is that symptoms can go away after repeated chronic exposure, making people unaware of the damage being done to their respiratory systems. But, even small amounts of ozone can be harmful, a Canadian study found that measurable bronchial reactivity can occur at ozone concentrations as low as. Even when not directly inhaled, ozone can be harmful.

For example, ozone can react to common household cleaners, such as terpenes, which are more commonly known in pine and citrus fragrances. In the presence of ozone, terpenes form formaldehyde, a Group 1 human carcinogen. Ozone can even cause rubber and plastic to deteriorate prematurely in amounts as low as 0.35 parts per million. Imagine what it does to our bodies.

Ozone should be avoided, even in small quantities, and the air purifiers that generate it should not be used. Another problem with these ionizers is that they can produce ozone, “and this is very bad in an indoor environment,” says Dr. James Sublett, former clinical professor and head of allergy and immunology at the University of Louisville. Ozone is a type of oxygen molecule produced by electrostatic reactions.

Although it naturally exists in the air we breathe, its concentrations tend to be very low. At higher concentrations, it can damage lungs and respiratory tissue, Sublett explains. If your home doesn't have a forced air system or if you're looking for something for your workplace, both Sublett and Edwards recommend a portable air purifier that has a built-in, replaceable HEPA filter. One of the most popular air purifiers you may have heard of are those that use “HEPA” filters.

Filtering air filters pass air through a filter, where polluting particles or gases are sequestered, and return clean air to a room. But again, if you place a HEPA filter in your HVAC system, you may be looking for problems, as some units develop problems due to increased pressure that results from pushing air through denser filter material. An air purifier circulates fresh air by removing airborne irritants that pass through its multilayer filtration. There is some popular controversy surrounding the extent to which air purifiers can reduce the presence of larger particles (such as pollen, house dust allergens, mold spores, and animal dander), but most of these large particles are deposited on home or office surfaces and cannot be removed with an air cleaner unless altered and resuspended in the air.

The air purifier market is booming, but a new study has found that some air cleaning technologies marketed for COVID-19 may be ineffective and have unintended health consequences.

At first glance, it may seem that ozone is a great way to remove pollutants from the air without the need for a filter or even fans in some cases. Mechanical filtration: These types of air purifiers draw in air that is mechanically forced through filters that remove particles in the air.

A HEPA air filter is made of very fine glass fibers randomly woven into a mesh material that folds to increase its surface area. The higher the CADR number for each pollutant, the faster the unit filters the air for contaminants in a given size range. But ion air purifiers, while primarily releasing negatively charged particles into the air to remove debris, have proven to be ineffective at actually cleaning indoor air and only become effective when they release extreme amounts of ions, which in turn also causes ozone production. We've seen quite a number of websites that warn against ozone-releasing air purifiers, so the answer should be clear to you now that you've seen what each type of air purifier does.

A mechanical air purifier uses an internal fan to draw air through a series of filters, trapping harmful particles before returning clean air to the room. . .
