I take it you're trying to help someone in your house with dust and allergens? Have you tried a powerful air purifier? Many air filters on the market do not do what Shaklee's airsource does. Three powerful technologies are combined to eliminate all sources of air pollution or irritants including airborne mold, bacterial, viruses, odors, VOCs, and the list goes on. It is silent and requires the change of a light bulb once annually so no messy filters to clean. I love it as it makes it smell like we have the windows open in the house. If I hadn't become a distributor, I would never have realized how serious indoor air pollution is. Because of all the chemicals we bring into our homes (and fumes we cannot avoid from carpet, furniture, dry wall, etc.) our indoor air pollution is now said to be 2-5 times worse inside than outside! It's no wonder we're developing allergies and sensitivities.
There are also other things you can do like reduce those indoor air pollutants. Switch to non-toxic cleaning products. Shaklee's Get Clean line is awesome and the products are concentrated so while it typically costs you more to go green, these eventually cost you a lot less. And they work - not something all "green" brands can actually do.
Let me know if you'd like more information.
Thanks,
