What do I look for when purchasing an Air Purifier?

One point to consider when choosing an air purifier is how fast the unit is capable of circulating and purifying the air. If the holes in the filter are too small, it will filter well at first, but at the same time it has a high resistance to rapid airflow. As a result, its purification ability is significantly lower as time goes by and the life span of the filter is shortened. The Zalmandn air purifiers have remarkable deodorisation power, high air circulation and collection ability with lower resistance to air, so the high purification can last as long as the filters.

HEPA vs 3M Filter
HEPA air purifiers use pleated High Efficiency Particle Arresting (HEPA) filters to trap allergens, along with a fan to pull air through the filter. The key advantage of the HEPA filter is the high efficiency in collecting dust and particles in the air. Consequently many air purifiers are promoted as having a HEPA filter, but the use of HEPA filters does not guarantee efficiency. With the introduction of the 3M filter technology in the Zalmandn range, the effeciency of the 3M filter is absolutely competitive with the high quality end of the HEPA filter products – check the CADR to confirm.

Why purchase an Air Purifier?

While air pollution is thought to be a problem related to outdoor air, the same pollutants can be found indoors. We spend up to 60% of our time indoors and our homes are not always the safe places we would like them to be.

Modern buildings are designed to be energy efficient so as to maintain temperature, but as a consequence they do not breathe. This allows air pollutants to accumulate inside the building, as they cannot escape. Sources of indoor air contamination include cigarette smoking indoors, gasses given off from poorly ventilated cooking appliances and heaters and other materials within the home that emit unhealthy chemicals. These chemicals, some of which are called volatile organic compounds (VOC’s), can cause ill health and they are found in carpets, chipboard, furnishing fabrics, clothing pesticides, cleaning products, toiletries, cosmetics and hobby products.

People can add to levels of indoor air pollution with recently dry cleaned clothing and perfumes. Perfumes can contain as many as 100 ingredients and are very potent additions to indoor air pollution.

What is a Chemical Cocktail?

All of these pollutants present together within any indoor environment are a ‘chemical cocktail’ the result of which is called ‘sick building syndrome’. Long periods of exposure to the ‘chemical cocktail’ can cause a large range of health problems.

What are some of the major indoor air contaminants, where do they come from and what are the health risks?
