Distribution, aerodynamic characteristics, and removal of the major cat allergen Fel d 1 in British homes.
Sensitisation to cat allergen (Fel d 1) is an important risk factor for asthma in the UK.
A study was undertaken to investigate the distribution of cat allergen in British homes, the aerodynamic characteristics and particle size distribution of airborne Fel d 1, and the method of removing it.
Dust was collected from 50 homes with a cat and from 50 homes without a cat, and airborne levels of Fel d 1 were measured in 50 homes with a cat and 75 homes without a cat.
Particle size distribution was determined using an Andersen sampler (8 hoursday) in 10 homes with cats.
This was repeated on five separate days in a house with four cats, and then one, two, four, seven, and 14 days after the cats were removed from the living room area.
The effect of high efficiency particulate air (HEPA) cleaner on airborne levels of Fel d 1 was investigated in seven homes with cats.
Samples were collected on two separate days from two rooms of each house concurrently, one of which contained the cat, one day with the HEPA cleaner on and the other day as a control.
Three one hourly samples were collected over a nine hour period (baseline, 4-5 hours, 8-9 hours) using a high volume dust sampler (air flow rate 6011min) and the air sample was collected onto a microglass fibre filter (pore size 0.3 mum). (...)
