Types of Air Purifiers

Ozone Air Purifiers

Ozone air purifiers take in air from inside a room, turn the oxygen within that sample of air into the gas ozone, and then turn the ozone back into oxygen before releasing the air. In the process, ozone air purifiers remove harmful particles from the air, including dust mites and molds. And they also take away any odors those particles create. With so many different brands of air purifiers available in the market, Finding the best air purifiers in UK is a time consuming task.

Ozone air purifiers have commercial and industrial applications, but are they safe for home use? New technologies may one day allow people to buy and use such purifiers in their homes safely, but until then, the answer is no. Exposure to any amount of ozone can cause harmful effects within a person’s body – some mild, some more threatening. Among the common side effects of ozone exposure are chest pains, obstructed breathing, a sore or irritated throat and coughing. Asthma patients may find themselves suffering from an intense and dangerous shortness of breath, and from a higher number of asthma attacks as well.

(Not only that, but some studies have indicated that ozone air purifiers are ineffective at removing many allergens from the air in the first place.) Ozone can also weaken immune systems, even in healthy individuals, and render bodies incapable of fighting off infections of the lungs and throat. And these health problems, as you might imagine, are often especially acute in children and the elderly. In short, ozone air purifiers can actually be more harmful to a person’s health than the particles in the air they remove.

UV Air Purifiers

UV air purifiers are devices that employ an ultraviolet light bulb to clean all the air within a given space. These machines are safe, quiet and effective, and they can give you get the healthiest air possible inside your home.

UV light has long been known for its powerful disinfectant qualities; it’s been used to sterilize hospitals for many years. There’s more than one kind of ultraviolet light, however. UV-A light is the kind of light they use in tanning salons; it’s harmless to humans in low doses. On the other hand, UV-B light can harm a person’s eyesight and skin. Then there’s UV-C light, sometimes known as “germicidal UV.” It’s this third kind of ultraviolet light that disinfects. UV-C is adept at getting rid of all kinds of microbes, everything from germs and fungi to bacteria and viruses, and it can even eliminate common allergens in the air.

UV-C light is used in UV air purifiers. In most UV air purifiers, however, at least one other kind of filter is present in addition to the UV light bulb. For instance, some purifiers employ UV-C light as well as a High Efficiency Particulate Air (HEPA) filter. HEPA filters trap airborne particles measuring 0.3 microns or smaller.

One aspect of UV air purifiers to look at before you make your purchase is how often you’ll have to replace the bulb. Some UV air purifiers require that the bulb be replaced once a year – or perhaps even more frequently than that. Other UV purifiers only require a new bulb once every three years. Usually, a purifier will include an indicator light that will let you know when it’s time to get a new bulb.

Room Air Purifiers

The air in your home could contain scads of particles and you might not even realize it. Most airborne particles are odorless and too small to be seen. But what you can’t see can hurt you, and if you inhale these particles and they build up within your body, over time they can create adverse health effects. However, were you to set up room air purifiers, you might notice major differences in the way you feel. For example, if you find you’re often stuffed up or sometimes have difficulty breathing at home, room air purifiers could give you clearer respiratory passages.

Buying room air purifiers involves making several decisions. First, where will you put your purifier? If you suffer from allergies, and you always have your bedroom window open in the spring and summer, then a purifier in your bedroom would be a natural choice. You might sleep better because you won’t be afflicted by pollen particles floating around your bed. On the other hand, if your dog spends a lot of time in your living room, then the living room would be a great place to install that purifier: it’ll remove pet dander efficiently. Or, if your kitchen smells smoky, it’s an ideal spot for an air purifier. And if it fits your budget, why not install room air purifiers throughout your home?

Room air purifiers have different air change rates, too. An air change rate represents the number of times in an hour a purifier can completely filter all the air in a given room. Many experts recommend an air change rate of six, meaning the air within a room will be completely filtered six times every hour. An air change rate of less than six could result in your breathing in more unwanted particles than you have to.
