Will an air purifier reduce the amount of dust in my home?
I dust everyday it seems and am constantly vacuuming because I feel like if there is that much dust on top of things, I can only imagine how much goes into the carpet. Will an air purifier help with the dust? Are there any products you recommend for helping reduce the dust?
Will humidifiers do the same as air purifiers?

It could be that your vents are dirty.. if you have central air or heating.. that would just keep blowing in the dirt..so make sure to vacuum in them or call in a professional cleaning..
An air purifier would help some yes but make sure its the right size for the room..and a quality one..
Only in that the dust that the air the purifier takes in will be trapped in the filter . . . Check your furnace filter (your furnace runs all summer if you have central air). Change your furnace filter every month (I put the date on the edge of the filter in permanent marker and on a piece of masking tape on the outside of the furnace to remind me the last time I changed it). If you buy the cheap ninety nine cent filters, a lot of the dust will go THRU the filter and out your air vents.
Humidifiers will help but not as well as a good furnace filter. Have a pro install a media filter, it is a big filter, about 3 inches thick that will remove more dust, especially if you let the fan run and will last much longer than standard 1 inch filters and pass the airflow much more easily.
make sure u get one for the room size and make sure t has ahepa filter
Yes! They are not, however, a solve all panacea, and are expensive. One with a high HEPA rating is best for treating allergy related problems. There is no way to eliminate today’s sorrowful environment! You will still have to dust, to no avail. Consumer Reports magazine has some good articles on the particulars .
