If you suffer from allergies then the MeacoClean CA-HEPA air purifier could help alleviate your symptoms. It is important to match the size of the room that you want to clean with the air flow going through the air purifier. The MeacoClean CA-HEPA 47x5 can move up to 236m of air per hour but to maximise cleaning, the air within the room needs to travel through the filter several times each hour. The MeacoClean range uses several stages of filtration to deep clean the room air and what makes the MeacoClean air purifiers different is the quality of filter that they use.
