An air purifier can make a huge difference to your quality of life. Whether you have a family member with allergies or you just want to make sure you are breathing in the cleanest air possible in your home, the MeacoClean CA-HEPA 47x5 air purifier is a great buy. This air purifier uses a multi-stage air cleaning system. The room air first moves across the pre-filter to remove larger particles such as dust. The HEPA filter removes smaller allergens, then the charcoal filter removes smells and volatile organic compounds (VOCs) from the air before the ultraviolet light works in conjunction with the photocatalyst titanium dioxide coating to remove bacteria and viruses from the air.    Step one: Check your allergy To select the correct air purifier, you need to know what you are allergic whether it's pet hair, pollen, dust mites or other.   Step two: Check your room size The MeacoClean CA-HEPA 47x5 can move up to 236m3 of air per hour. The more times that the air within the room passes through the air purifier, the cleaner that air will become. This is why it is important to carefully size the air purifier to your room size. Finishing touches The MeacoClean CA-HEPA 47x5 air purifier features responsive feather-touch controls that change the settings quickly and easily. A filter replacement indicator will tell you when to replace the filter set, which is usually once every 6 months on average. The MeacoClean range has been designed to offer you a superior air cleaning solution to your allergy problems at an affordable and sensible price. You can buy the MeacoClean CA-HEPA 47x5 safe in the knowledge that you are buying an air purifier that really will make a real difference to your quality of life.
