The question of the afternoon is…can indoor air pollen levels that is nice be better than outdoor air quality that is nice plus natural? That all depends on a lot of things.
Indoor air quality that is fantastic because of a whole cabin air purification method of course is unnatural quality air.
Although it can not harm you in any way, shape or form, whole cabin air purification systems creating nice air quality is only the best if you have lousy outdoor air quality. Or, if it is so hot outside, that you have to be indoors with your central HVAC method with the thermostat cranked down all the time. Then, a whole cabin air purification method is all that you would have to be able to breath in fantastic indoor air pollen levels. If you have quality air outside all the time, you would not need to invest in a whole cabin air purification system, plus you would be able to leave your windows opened quite a bit to get that fresh air quality flowing through your home. That is what I do in our beach cabin down the shore in the summer. The heat is not too poor at night, so I turn off the central cooling system, plus after that I open up all the windows plus let that attractive ocean air quality into the house. It absolutely makes a huge difference. I do not have a whole cabin air purification method down there. Only in our cabin at home. That is because the air quality here can get pretty bad.
