Just wanted to share how we went about saving lots of money on carpet. We just bought a house and the previous owners had 2 cats. We are both allergic (especially my partner) and considered installing all new carpet (finished basement) because when we looked at the house my partner was already having bad allergic symptoms just after a few minutes in the basement. It was a shame because the carpet was really not that old or bad. I did a bit of research and came up with this product:
http://www.allergystore.com/xmite_antiallergen_carpet.htmWorks on mite poop, pet dander, and other allergens. It denatures the proteins in the allergens, rendering them neutral.
We treated the carpets before we moved in (it was super easy using a big clean broom) and the results were amazing. It's been almost 2 weeks and we have NO allergy symptoms. And the carpet feels clean, too. For a few days there was a faint "cleaner" smell in the basement, but nothing bad, really. In addition, I got a gallon of the ADMS spray for other surfaces (I had empty spray bottles to refill).
New carpet quote:$1500
Allergen denaturing agents + big broom + a little bit of work: $125
Savings: $1375
Woohoo!
