If you are a smoker or a pet owner, the odds are that the air you breathe inside the home is not as healthy as it should be; this is why you should begin thinking about buying an air purifier. However, any person can benefit from having an air purifier regardless if he has a pet or if there is a smoker in the home or not.
If you have decided to get a purifier, it will not be in your best interest to just go in the shop and get one without taking time to know all you need to know about air purifiers since you may end up with one that has a low performance.
It is better if you learn about the qualities of air purifiers before going out to buy one. You can easily get all the information about them online. You can get comments, product rating and reviews online; within these reviews, you can also get reviews about the most popular air purifiers. When you know someone who uses one, you can ask them about the performance of their model and ask them for their suggestions as to the best one out there. If you get feedback from people who already use a purifier, it will be the best way of learning about its performance.
Besides the quality of the air purifier, take time out to consider the size of the purifier you want to buy. When you hear about their sizes, it does not mean how big or small the machine is but the size of a room that it can clean. Cheaper air purifier clean smaller rooms, if you have to use one for a bigger room, you will have to buy an expensive model.
Another factor to consider is how much you will pay for it. The air purifier does not only cost you once, you will have to pay for the maintenance as well. Some of them are filter-less while others are not. For one that uses the air filter, it needs changing regularly and the cost of those filters may be too high. Some of those filters may need to be changed as often as once in a year or two years, others can be changed just within months. Most of the air purifiers are expensive, before buying any make sure that it has a warranty to be on the safer side!
