Air purifiers can be found in any department or big box store. There are hundreds of models available on the internet. It was recently reported that Amazon had over 21,000 air purifier products listed. Some of the products listed on Amazon are truly great products, others, not so much. When you are purchasing an air cleaner for smoke, look for these key elements.
Does the air purifier you are looking at have a strong enough fan? Some air purifiers have no fans at all, some have undersized fans. The amount of fan power to clean the air in a room is crucial. Many so called HEPA units on the market do not have enough power to pull the air through the filter. Or they will pull so little through there is not enough circulation to clean the room. The best air purifier for smoke should clean the air at least 6 times an hour in the entire room. More cleaning cycle at a lower efficiency is better than low cleaning cycles at high efficiency. The free flow design of an electrostatic air purifier shines in the number of cleaning cycles. LakeAir Products use high power fans and blowers.
