As with any contagious disease, the COVID-19 pandemic has done more than just rob us of lives. It has also forced almost the entire world to stay indoors and to social distance from loved ones and friends. With everyone cramping into a fishbowl life, a new question arises: Is our home truly a safe haven?
According to the US Environmental Protection Agency (EFA), indoor air is 2 to 5 times more polluted than outdoor air and is often compromised by PM2.5 ultrafine particles, allergens, bacteria, harmful gases as well as air humidity – most of which could affect our health. No matter how often you vacuum a room, there will be particulates that float in the air as they are too tiny and light to settle on the ground for long. The higher the concentration of particulates in the air, the higher the presence of bacteria and viruses.
Published in the National Library of Medicine, a paper reviewed six studies conducted over 10 years on the association between indoor air quality and its effects on respiratory health among Malaysian schoolchildren. Conclusion: children exposed to poor indoor air are more likely to suffer from respiratory illnesses.
The serious haze that occurs sporadically worsens the situation, to the extent of halting traffic movement and closing schools. A report prepared by the Academy of Sciences Malaysia says it all: “During the 1997 haze, Kuala Lumpur General Hospital recorded a substantial increase in cases of upper respiratory tract infections, conjunctivitis, and asthma.”
Aside from regularly washing hands, wearing a mask in public and sanitizing hard surfaces in the house, what else can you do to protect your home?
Lancet1, among the world’s oldest and independent general medical journals, has also stated that “proper conditions indoors have the potential to reduce the spread of COVID-19; conversely, improper conditions, such as limited ventilation and filtration, can make indoor environments high-risk settings.” The Philips Air Purifier 3000i Series can eliminate these risks by removing up to 99.9% of viruses and aerosol while purifying the air of contaminants (in a 20m2 room) in less than 8 minutes using AeraSense, a built-in smart technology that continuously monitors the air and detects particulates, gases and allergens in real time. The sensor is able to identify the myriad of indoor pollutants such as pollen, dust mites, mold spores and even pet dander.
This product was developed by Royal Philips – a leading health technology company headquartered in the Netherlands. Aside from consumer health and home care products, it is also recognised for diagnostic imaging, image-guided therapy, patient monitoring and health informatics, and has become a global leader in air purification with a team of over 100 scientists, doctors and engineers working on it.
Philips NanoProtect Integrated HEPA and active carbon filter makes it possible to remove from the air up to 99.9% of viruses as well as 99.9% of toxic fumes (aerosols) from paint, insecticides and synthetic materials. The filter was designed to have low airflow resistance, which maximizes the cleaning speed and efficiency in aerosol removal, as measured by Clean Air Delivery Rate or CADR. HEPA filters are safer and more effective than UV devices and ionizing air cleaners. UV radiation is harmful to humans and ionizing air cleaners produce ozone which is harmful to the environment.
The size of SARS-CoV-2 (or COVID-19) virus is estimated to be between 50 –140 nanometers (nm). Philips air purifier removes 99.97% of particles as small as 3 nanometers (0.003μm2), smaller than the smallest known virus3, from the air which passes through the filter. A similar performance is expected for SARS-CoV-2 (COVID-19) aerosols4.
Philips Clean Home+ app allows you to check real-time indoor and outdoor air quality. With this free app, you can control your purifier anytime, anywhere, receive air quality and allergen management advice. It reflects the amount of pollutants filtered and how much life your filter has left. Siri and Amazon Alexa compatible, you can command the purifier with just your voice.
The purifier also comes with auto-ambient lighting which automatically adjusts according to the environment in the room. Keeping it running while you sleep will not be a problem as it is ultra-quiet and nonintrusive to light sleepers.
During the launch of the product, Nicholas Lee, Personal Health Leader of Philips ASEAN Pacific said, “With the Philips Air Purifiers, we want to provide our customers with the latest intelligent, personalized solutions that can help them breathe easier by creating healthy indoor spaces.”
“Philips products are subjected to rigorous testing before they are released to the market. We conduct life and durability tests. Our Philips air purifiers have been validated to perform under continuous operation in an indoor environment for three years,” added Lee.
Philips air purifiers are developed and manufactured in compliance with all safety regulations and standards (IEC/EN 60335-1 IEC/EN 60335-2-65). They can be used safely in a wide range of indoor environments, including homes, offices, schools or dental clinics. This study from the Goethe University of Frankfurt am Main reports that four Philips Air Purifier 2000 Series AC2887/30 operating in a classroom with 27 students can remove 90% of aerosols within less than 30 minutes5.
