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.. Multi-stage air purifier. 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 finally, the ultraviolet light works in conjunction with the photocatalyst titanium dioxide coating to remove bacteria and viruses from the air.. The ioniser helps to remove dust from the air.. 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.. Step one: Check your allergy. To select the correct air purifier, you need to know two things: what you are allergic to and the cubic air volume of the room that you want to clean. This is where air purifier selection normally goes wrong: the filter and the allergy don’t match and so often the purifier is too small for the room and doesn’t clean the air properly.. MeacoClean air purifiers can remove:. Step two: Check your room size. 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:. Number of air changes per hour and room size. 3. 4. 5. 6. 7. 8. CA-HEPA 47x5. 78m3. 59m3. 47m3. 39m3. 34m3. 29m3. To convert from cubic metres to cubic feet multiple the above number by 35.3 i.e. 29m3 equals 1024ft3. If your rooms are larger, why not try the MeacoClean CA-HEPA 76x5 Wi-Fi Air Purifier, which is designed for bigger spaces.. CADR Rating. Another way to compare air purifiers is to look at their CADR rating.. Clean Air Delivery Rate score. Smoke. Dust. Pollen. CA-HEPA 47x5. 135. 142. 151. CADR is a respected, independent, internationally recognised test standard. The above laboratory scores show how effective the air purifier is at cleaning the air. Use these figures to compare the MeacoClean with other air purifiers as part of your decision-making process. When researching ask for air flow rates to see how many times an hour the air will pass through the air purifier. If the purifier uses a charcoal filter, ask how much charcoal is in the filter: our 47x5 purifier uses 130 grams of enhanced coconut charcoal. Essentially, the heavier the filter, the better. Coconut is a very effective charcoal.. 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 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..
