So, youve finally decided to invest in an air-purifier. No doubt youve been bombarded with online pop-up ads and the usual sales spiel about air-purifiers during your research for the ideal air-filtration system for your home or office. Perhaps youve even more confused now than before! Here are some aspects you should consider before making your final purchase, to help to decide which air-purifier is best suited to your specific needs.

How much does it cost to maintain the product in the long run?

The initial purchase price is not the only investment that you will be making in this product. That is just the tip of the iceberg, so to say. Dont buy the cheapest model in the market only to find out that the replacement filter is steeply priced. What you need to consider are other costs attached to running and maintaining the air-purifier. For instance, if the purifier has a filtration system, how often does it need replacement and how much will that cost? Are there any other components that need replacement periodically? Electricity consumption is another factor to take into account. Check the wattage of the air purifier. Have you made a note of the warranty or guarantee period bundled with the product?

The noise factor

What is the noise level trade off vis--vis health advantages of the air-purifier that you are willing to endure? A higher wattage air-purifier may be able to clean a higher volume of air, but it might also make more noise. If noise level is an important consideration for you, perhaps you can request the company for a demonstration. Will you be able to return the product if you find it unsatisfactory? Do check out the money-back guarantee, carefully, if offered.

Which parts of your home need purification?

Your choice of air-purifier will naturally depend on your need to purify. Do you need it specifically for one bedroom? Are you buying it mostly to remove pet hair? Would you prefer it to be portable from room to room? So, the thing to take into account is the coverage area that the air-purifier will decontaminate. Most units are portable but there are others that can be affixed to your homes central heating and cooling units. This option will certainly cover your entire house but may not be as effective as a stand alone unit for a single room. Do note the air-purifiers specification on the amount of area it will purify.
