The MeacoClean CA-HEPA 47x5 can move up to 236m3 of air per hour. The more often the air from your room goes through the air purifier each hour the cleaner the air will become. If your symptoms are mild then three times an hour will be fine, five times an hour will give better results and a factor of seven or eight times an hour should be used if your allergy is severe. The table below gives you an indication of the room sizes that the MeacoClean CA-HEPA 47x5 can purify for you. The MeacoClean CA-HEPA 47x5 air purifier features feather touch controls that change the settings as if by magic as you run your fingers over the panel.  A filter replacement indicator will tell you when to replace the filter set (approximately every 6 months). The enhanced charcoal filter contains 130g +/-20g of charcoal for superior odour removal.  The enhanced charcoal and HEPA filters have a rubber gasket seal to make sure that no air can pass through the air purifier without being cleaned. 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.
