If you’re thinking about buying a new air purifier or have made the decision to switch to cleaner air, this article is for you. We’ve done a lot of research on air purifiers and their pros and cons. After years of research, we’ve put together a guide that will help you find the best purifier for your needs. It’s important to remember that even though an air purifier might help remove some harmful contaminants from the air, they are only one part of the solution. You’ll also need to change your lifestyle and do things to protect your family from pollutants as well.
Overall, there are two main categories of air purifiers, those that use filters and those that don’t. For example, ionic air purifiers are energy efficient, but they won’t eliminate particles like pollen. There are room size and portable ozone air purifier filters as well as larger models.
With a large number of pollutants in our indoor environment, it’s no surprise that many people suffer from symptoms such as headaches, asthma, allergies, and fatigue. A healthy immune system can reduce the risk of these symptoms, but most of us don’t get enough exercise or eat a balanced diet to support optimal immunity levels. Another solution is to use air purifiers to reduce airborne allergens, pollutants, and airborne contaminants. Inhaled allergens are thought to negatively affect cognitive functions, increase blood pressure, and lower endorphins and serotonin. Allergens are thought to be released through breathing and transfer through the body via mucus and the air.
Room size air purifiers are available in two basic types; electromagnetic air purifiers and light air purifiers. Electromagnetic air purifiers require a direct electrical current to operate, which makes them less energy efficient than light air purifiers. Also, they emit ozone, which can irritate your eyes. Light air cleaners however use filters to absorb airborne allergens such as pollen and airborne pollutants, thereby improving respiratory health and decreasing the number of dust mites and other allergens in your home or office.
One of the most common claims is, “Air purifiers are good for you because they kill germs”. Although this may be true in the sense that they do reduce the number of particles in the ambient air, the larger part of the claim is that they kill airborne germs (bacteria, viruses, and other microorganisms) with an efficiency greater than conventional filters. This may be technically true, but the fact is that they rarely kill viruses, which are much larger than bacteria and lower in surface density. Moreover, as we have seen, viruses are rather easy to inhale; therefore, the benefits of an air purifier to an individual are primarily health improvement.
Air purifiers also claim that their technology reduces airborne allergens, thus improving respiratory health. However, there is no proof that an air purifier effectively reduces allergens, especially at a low ach rating. It is also important to note that at a low ach rating, some air purifiers may actually increase the arch index (measured using a laboratory device). Air purifiers are only good for the indoor environment; they are not good for outdoor air.
