I have purchased Eternal air purifier from the trustworthy Kent Ro The purifier has several functions, such HEPA(High Efficiency Particulate Arrestor) dust collection technology from Japan.
The three stage filtration process gives you an excellent level of Air Purification. Kent Air-Purifiers uses tested and trusted a unique designed PRE filter which catches and removes large particulate matter with high efficiency, It reduces bad odour from the environment if any. It remove any smell.
The product itself is very effective when it comes to giving clean air. For people with allergies and breathing problems like me you can literally feel the difference.
