Buying an air purifier makes great sense, especially if you have young children in your family. An air purifier removes pollutants, allergens and small particles in your home, giving you cleaner air to breathe. If any members of your family are susceptible to respiratory problems, it’s good to have an air purifier at home. And it comes in especially handy when there’s a haze.
If you’re looking to invest in an air purifier, take note of these shopping tips:
1. COVERAGE AREA
Each air purifier will have a certain area of coverage. You’ll need to buy one that has an area of coverage suitable for the size of the room it is meant for. A small air purifier should be sufficient for a bedroom, but you’ll need a bigger model if it’s meant for a larger space such as a living room. For best results, choose an air purifier that has a coverage that exceeds the total area of the particular room space.
2. NOISE LEVEL
If you’ll be using the air purifier in your bedroom while you’ll be sleeping or in a study where you’ll be working, check the decibel level of the appliance. An air purifier that comes with a built-in fan can usually clean the air more efficiently. While a faster fan speed means it’ll be able to purify more air, that also means it will generate more noise. At the store, test the sound level of the model you’re interested in before purchasing it.
3. AIR FILTERING TECHNOLOGY
Check what type of air filtering technology the model uses. For example, a HEPA (high efficiency particulate air) filter can get rid of very small particles of 0.1 to 0.3 microns in size, filtering out 99% of particles. HEPA filters can eliminate allergens and asthma triggers such as pollen, mold and dust mites and can even filter viruses and bacteria. A HEPA filter comes in especially handy when there is a haze because it can get trap the particulate matter from the air pollutants. You should get an air purifier that comes with a HEPA filter.
Another type of filter that is common in air purifiers is the carbon filter, which is used to eliminate bad odours, gases, chemicals, fumes and cigarette smoke from the air. They’re very helpful for those with respiratory conditions.
Air purifiers will usually use a combination of air filtering technologies, so do your homework. An air purifier that comes with both a HEPA and carbon air filter will be sufficient to clean the air in your home.
4. OZONE FREE
You should also purchase an air purifier that is ozone free. Some air purifiers release ozone as a byproduct, such as those with ionisers. This could become a lung irritant and trigger reactions in those with asthma.
5. ENERGY CONSUMPTION
If you plan to turn on your air purifier for a significant amount of time everyday, then it’s important to check the energy consumption of the model. Look for models which are labeled as energy-efficient.
For an air purifier to be efficient, you’ll need to maintain it. In most cases, you’ll need to replace the filter regularly. Therefore, it’s important to check how long the filter will last on your particular model so you’ll know how much it’ll cost you to replace the filter each time. Some other filters may be more cost-efficient as they can be washed multiple times before being replaced. Also check whether any parts of the air purifier need to be replaced and how easy it is to get those replacement parts.
As with any electrical appliance, you should get an air purifier that comes with a warranty – of at least one year.
8. SIZE AND PORTABILITY
You may not need an air purifier in every room. So it’s a good idea to buy one that is portable and compact enough so that it can be moved from room to room easily. Check the dimensions of the model so you can ascertain where is the best position to place the air purifier in each room.
