9 Factors to Consider When Buying An air Purifier
There are so many different kinds of air purifiers on the market that you may feel puzzled when you try to buy one. Below are the main factors you need to consider when you buy an air purifier.
Removal & collection of particles
HEPA air filters are perhaps the most efficient at removing pollutant particles from the air in your house, the primary contaminants that should be disposed of. Ionizers without a filter are also able to eliminate particles, but fail to collect much of them. There are several filters which seem to have no effect on particulates. For example, isolated UV purifiers or ozone air purifiers have little success in capturing dust or other allergens.
2. Elimination of odor
The best air filter in terms of odor elimination is an ozone purification and activated carbon air filter since ozone is extremely capable of killing the bacteria that brings annoying odors, while activated carbon is exceedingly good at absorbing odors. However, excessive ozone is not healthy since it is a little bit irritating. Thus, it is recommended that you turn off the ozone filter when it is not in use.
3. Capture of chemicals, gases, & smoke
Activated carbon air filters are the most absorbent type of filters available, and really do a good job in capturing chemicals, gases and cigarette smoke.
4. Destroying micro-organisms
Ultraviolet light is the most efficient in fighting against micro-organisms, and manages to destroy bacteria, germs, fungi and viruses. Thus, it is also beneficial in disease prevention. Ozone and negative ions are also qualified for destruction of certain micro-organisms.
5. Filter sanitization
Air filters may become the breeding ground for micro-organisms since the fabric therein enables them to attach to the captured pollutants and then reproduce or breed. So it is really necessary for air purifiers to be fitted with a separate sanitizing device, or the breeding micro-organisms will get back into the air in your house. A germicidal UV lamp can easily solve this problem, while an ionizer or ozone generator may also be relatively effective.
6. Purifying coverage
It is a misunderstanding that one portable air purifier is powerful enough to purify a whole house with several rooms since each purifier has limited coverage. The best way of keeping your home clean and comfortable is perhaps the use of multiple portable air purifiers. Additionally, portable air purifiers are much better than in-duct ones, for the former are more effective and convenient than the latter.
7. Price and Maintenance Cost
It is not always the case that expensive air purifiers have a first-class performance. Affordable ones are satisfying for the majority of people. Therefore, price is not in proportion to performance sometimes. Additionally, price doesn’t simply equal what you pay.
Most air purifiers demand extra maintenance costs. You have to buy replacement filters at intervals, usually three months to one year. So it can be a large sum of money when you consider both the price and maintenance cost.
8. Electricity consumption
Electricity consumption is another factor that should be taken into consideration when you buy an air purifier, for your electricity bill might be astonishing if you use a unit with a lot of power. It is better to buy energy-saving air purifiers that not only save you money but are also good for the environment.
As household appliances, air purifiers truly make our life more convenient and pleasant, but also bring some concern, and noise is just a typical example. Many powerful air purifiers can be very noisy on some occasions, but there are still some which produce little noise. In most cases, the noise is hardly noticeable when the unit is set at low or median speed.
In conclusion, the above nine points are the main factors you need to consider when you buy an air purifier.
