If you're buying an allergy air purifier, you want to buy once and buy right. To be effective it needs to be able to clear the air of potential triggers 24 hours a day, be economical enough to allow you to operate it, last a long time so you are not constantly replacing the purifier and buying replacement filters. Here are 5 things that you should see in the fine or not so fine print before you buy.
Durable Motor-First and foremost you need a good motor. Look for a permanent split capacitor motor that is rated for continuous high RPM (revolutions per minute) which allows long life duty. A motor that is also mounted on shock absorbers will make for quiet operation, which will allow you to have 24 hour coverage without even noticing it's there.
Steel Housing-This is a really important feature because purifiers made of steel do not off-gas like plastic cleaners often do when the motor heats them up. The last thing you want to do is pay for a machine that sends harmful chemical fumes into your home. Steel construction guarantees that the only by-product is fresh, clean air.
Four Stage Filtration Process-A purifier with a 4-stage filtration process means it has 4 filters working to clean your air rather than just one. This means it will last longer and eliminate a wider range of pollutants more effectively. It also means less time and money spent in buying and installing replacement filters. Pre-filters, generally the outer most filters, should be available cheaply and separately if you choose to extend filter life even further.
Maintenance-Knowing what you have to do to keep the cleaner operating in top condition before you purchase it is a must. Make sure it requires very low maintenance, and does not require washing, spraying, or recharging of the filter, which are all time consuming procedures. Doing anything with a filter full of contaminants on a regular basis risks having all the pollutants that you are spending money to eliminate released into the air again. Check also to make sure it is flexible in its placement in your room. A cleaner that only needs a six inch clearance means it can be placed anywhere rather than in the center of the room as some require.
Owner's Manual-You should be able to view the manual in its entirety and even download it if you choose. Reading through this before you buy makes you aware of many things that you may not have thought of. Having access to this information means that the company is open and honest about their product, and you can buy knowing what you're getting, which means no surprises for you once you've made your decision.
