Brief Summary:
Exposure to airborne allergens and pollutants is linked to symptom severity of allergies, asthma and other respiratory problems. In this study an air purifier using photo-electrochemical oxidation technology (PECO) will be used in the home environment of study participants. The investigator will assess the reduction of symptoms from allergic rhinitis/conjunctivitis and asthma.

Condition or disease Intervention/treatment Phase
Asthma Allergic Rhinitis Allergic Conjunctivitis Other: Active air purifier in respiratory allergies/asthma Other: Sham air purifier Not Applicable

Detailed Description:
The purpose of this study is to assess the efficacy of the portable PECO air purifier in reducing symptoms from allergic rhinitis and asthma. Using a randomized, double blinded placebo, controlled trial we will be then able to assess if there are any changes after the use of the PECO air purifier after completing an initial baseline survey & comparing to the exit survey. This is a double-blind study, which means that neither the participant nor the investigator knows which device is being used until after the trial is over.

Arm Intervention/treatment
Experimental: Active air purifier arm
Active portable air purifier for 1 month at bedside
Other: Active air purifier in respiratory allergies/asthma
Continuous use of air purifier to improve allergies and asthma control

Sham Comparator: Sham air purifier arm
Placebo portable air purifier for 1 month at bedside
Other: Sham air purifier

Primary Outcome Measures :
  1. Control of Allergic Rhinitis and Asthma Test (CARAT) score [ Time Frame: 4 weeks ]

    CARAT will measure the change in control scores of respiratory allergies and asthma.

    Scale 0 (Worse control of allergy and asthma) to 30 (Best control of allergy and asthma). The higher score the better control of allergy and asthma.

    There are 10 individual questions, scoring from 0-3.
