Removing Cat Dander from a Carpet

Master Yoda

Hello.

I have very serious cat allergies where i cant stay more than an hour at a persons house without getting sick in terms of breathing and watering eyes.

I will be moving soon to an apartment. The apartment is just what I want in terms of price, location, size and design. However I have one major problem, the previous tenant (4 months ago) had two cats. The landlady informed me that the carpets have been shampooed already and would be done again prior to me moving there. I really want this apartment but im not sure if the shampooing will be enough. I own a Hepa air filter which should help. I heard of a product called X-Mite, but i dont know if it really works.

I was thinking of asking the landlord a weird question. Asking if I could stay at the apartment for an hour or so to see how I react... if there is dander i would react within minutes. If i am fine I assume all would be well.

My question is does the shampoo (i guess steamed... i will ask) very effective removing dander.. Also the walls have been repainted but I doubt that would make a subtle difference. As for ventalation I believe it is natural gas heat.

I am thinking of taking allergy shots which would improve my tolerance.

Please reply soon, and have a good day.
