Air Purifier tip 5

When trying to decide on an air purification system, the first question that must be answered by you is, "Why do I need the system"? If it is due to a medical condition has your Dr recommended it? Has the DR referred you toa specdific brand? Ther are to many companies trying to SELL something tht is useless when installed,too expensive for the results achieved, and not functioning as promised. If you can give a true YES tjo needing athe sytem and can afford it, check with various air conditioning services and compare their offerings. Check with the BBB for problems with the venders. Get everything on a signed contract by an officer of the company, not the salesman! ASk for references of those who have the same system which you are considering. Check out the references, in person, if possible. Pay by credit card, not cash or check. If you decide to purchase a system, enjoy it.
