Traditional cleaning methods inadequate for removing dust mites, cockroach allergens: Study

Singapore: Bacteria, dust mites and cockroach allergens continue to be present in homes and cars even with regular cleaning through traditional methods, a joint study conducted by Dyson and FICCI Research and Analysis Centre (FRAC) reported on Tuesday.

The results of the study titled 'Indian Household Hidden Dust Study 2018', highlighted that the tradition methods like dusting, sweeping and mopping could not remove bacteria, dust mite, dog and cockroach allergens that were found in mattress surfaces and sitting and playing areas, among others.

“Indian homes are commonly seen to have clean floors, furniture and seemingly neat and tidy beds. Many might be surprised that by investigating the hidden dust from these homes, we found that cockroach allergens, dust mites, mould and bacteria were commonly present,” said Shantanu Khandelwal, CEO, FICCI Research and Analysis Centre (FRAC).

He further added, “Often not visible, these dust particles can trigger allergy symptoms particularly in people who are predisposed towards allergies.

The study was conducted on 100 urban homes across three major cities in India – New Delhi, Mumbai and Bengaluru, to collect hidden dust samples from carpets, mattresses, sofas and cars after the daily cleaning ritual of sweeping, mopping and dusting was performed.

“Dust mite and cockroach allergens are common triggers of all-year round allergy and asthma symptoms. Most of the times, the problem is too small to notice – while the home might appear clean, it is the dust and dirt that can cause allergic reactions” said Dr. Vikram Jaggi, Director of the Asthma Chest & Allergy Centres.

House dust mites and saliva, faeces and shredding body parts of cockroaches can trigger both asthma and allergies.
