Air cleaners or air purifiers are very helpful. Portable units should be placed in the bedroom at a location where the clean air flow is across the head of the bed. Larger units are also available which are incorporated with your existing forced air heating system. Both appear to work well, but the HEPA filter is thought to be the most efficient. Air cleaners may be rented to assess usefulness.
Rental fees are usually applicable to sale price.
Tobacco smoke is an irritant to the respiratory system and smoking should not be allowed in the home. Nasal steroids provide impressive treatment for allergic rhinitis. They should be used daily, as their benefit derives from suppressing both the short and the long term inflammatory allergic response. All the nasal steroids have similar efficacy. The newer nasal steroids have seemingly fewer side effects, i.e. nasal irritation and bleeding and require only once a day administration.
