I was using a cheap vacuum for a while without considering the possible troubles.
Unless the vacuum has HEPA filter inside, a lot of dust and good particles will get shot out the exhaust and will redistribute throughout your house after becoming airborne.
It’s like taking all of those particles off the cement and carpet and blowing them into your breathing air. That’s why I was adamant with our fiance about purchasing a nice vacuum last year when our old 1 finally died. I convinced him that the improvement in our indoor air quality would make it worthwhile. Since he has asthma, this fact appealed to him and eventually he agreed. Every one of us went on the internet and compared reviews with the models we found at a local supercenter. After narrowing down the best vacuum, we brought it house and started using it. You can lengthen the life of media air cleaner filters using a vacuum, as it will pull any dust that has collected on the inside surface. As long as your vacuum has a HEPA filter inside, you don’t have to worry about it redistributing that dust back into your house and it’s indoor air. I like being able to extend the life of our media air cleaner filters by vacuuming them clean at least once a week. The replacement filters are costly and are not as easy to find unless you purchase them all off the internet. Even so, our media air cleaner’s filter is $20 brand new, which is nothing to scoff at. This is why I’m so diligent about keeping the dust vacuumed-up correctly.
