Brief Guide to Personal Air Purifiers
A compact purification device can be just as effective as a bigger unit, but the main difference is that it can’t purify nearly as much air. A large unit is great for purifying a large room or space, but a personal unit is much better for a small space. With the help of a personal air purifier, you can eliminate smoke, odor and airborne contaminants.
At any given moment, the air around you could be filled with thousands of harmful airborne particles, and if they aren’t eliminated, they can make you feel sick and have a negative impact on your health.
What Are They?
An air purifier is a device that removes pollutants, contaminants and allergens from a room. They are sometimes called personal air purifiers because they purify the air in a room rather than the whole house – as opposed to filters you can put in an HVAC system.
The first patented air purifier was invented by Charles Deane in the 1800s when he tried to figure out a way that firefighters could avoid smoke inhalation. His device had a pipe that allowed the air breathed in to escape, while another pipe at the back of the helmet was supposed to be pumped with air by bellows. Later this was improved by a filter.
HEPA filters then came to be in the 1950s – short for High Efficiency Particle Arrestor. They were invented during World War II, when the US Atomic Energy Commission was trying to produce something that would filter out tiny radioactive particles from the air.
A HEPA filter works by trapping very small particles in the air, which are about 0.3 micrometers in diameter. They don’t remove odors however, so air purifiers often have carbon material in them to absorb gases and odors.
Who Can Benefit?
If you are prone to sneezing a lot this may be a sign that you need an air purifier. Good air purifiers have HEPA filters which filter out many airborne allergens such as pollen, pet dander and dust mites. Some air purifiers also have carbon filters which will filter out cooking fumes and tobacco smoke. Studies have shown that an air purifier can help with allergic respiratory diseases.
If the air in your home smells stuffy or stale then you can also benefit from an air purifier, as it will help you get rid of all those unwanted odors. If you see a lot of dust building up regularly, an air purifier can also help with this. It won’t completely get rid of dust, but it should keep it down.
An air purifier can even improve your health if you have a lung condition such as asthma, emphysema or COPD. These conditions are often made worse by irritants in the air, so reducing the pollution should also help reduce symptoms.
Congested airways can increase the likelihood of snoring, so if you snore a lot you might want to look into getting an air purifier as well. It will clean the air so that there are a fewer allergens to congest your airways. Pet owners also benefit from air purifiers, since they can remove pet dander and odors from the air. This will not only make your house less smelly, but also more accessible for friends and family members who are allergic to pets.
What To Look For?
Look for an air purifier that has been certified by AHAM (Association of Home Appliance Manufacturers). They rate them with a number between 0 and 450 CADR (Clean Air Delivery Rate). This number indicates how quickly the device filters dust, tobacco smoke and pollen out of the air – which are the three most common household particulates. AHAM also suggest the size of room for which it would be best suited.
Air purifiers that are ozone generators are not recommended by many experts now, since ozone irritates the lungs. Electronic air cleaners produce small amounts of ozone too, but they are very efficient and don’t need filters to be changed.
HEPA filters are the other main kind of air purifier – they are effective and produce no ozone. However their filters do need changing about once a year, so it is worth checking the price of replacement filters before buying. What you choose also depends on what you are trying to get rid of the most. If your problem is allergies then you need to look for something that removes allergens well – which is usually HEPA filters.
If you suffer from asthma or find that odors and fumes irritate your lungs, then you will want to look for one that has carbon filters to filter out gases. There are also smoke air purifiers designed specifically to filter out smoke and fireplace fumes.
Air purifiers work on a room by room basis, so you will also want to consider the size of room you want to purify – although you can of course move them around and purify each room one by one. Then compare the square footage to the recommended square footage by AHAM.
Consider if you want any bells and whistles – there are often additional features available such as digital controls, remote controls, different fan speeds, timers and air quality sensors. Also if you can, look at how noisy it is. Some air purifiers are noisier than others, since they need a motor to run.
What To Avoid?
Avoid using an ozone type air purifier as the ozone can actually act as an irritant. It is better to use a filter based purifier.
Will an air purifier cure me of my respiratory disease?
No it won’t cure you, but it should help reduce your symptoms by reducing the amount of pollutants and allergens in the air.
How much maintenance does an air purifier need?
If you’re using an air purifier with a filter then it depends on the type of filter and how often the manufacturer recommends that you replace them. HEPA filters often last a year, whereas carbon filters often only last for 6 months. There are other types of purifiers that don’t have filters so won’t need maintenance of that type. There are others that have a combination filter, so you would need to check in the instructions.
Do ionizing air purifiers emit ozone?
Some of them may, but they aren’t the same thing. There are purifiers that work by emitting positive and negative charges in the air, which makes particles stick together and get caught more easily by HEPA filters.
Can they be run cordlessly?
Generally air purifiers need to be plugged in because they have a motor that runs.
The best personal air purifier can have a dramatic impact on the air you breathe, and when used in a small space, it can significantly improve air quality. It might not be as powerful as a standard unit, but it’s perfect for cleansing the air in small spaces, and it can remove 99.9 percent of airborne pollutants.
