It might seem a little strange at first, but homes these days are built so well, they’re much more airtight than the ones our parents and grandparents grew up in. While that’s good when it comes to energy savings, it brings about another set of issues when it comes to the quality of the air you and your family breathe indoors. In fact, when you take into account that the U.S. Environmental Protection Agency has gone on record stating the air inside your home is in fact much more polluted than the air outside, the need to find the right air purification system becomes clear. Here are a few pointers to help you find an efficient and affordable unit. Make sure the product you’re looking at is efficient. That means regardless of the model, it should be able to handle any of the categories of indoor air pollutants. These include allergens, dirt, dust and pollen that are breathable particles, viruses, bacteria airborne mould spores and finally chemicals, vapours and odours. A good starting point in choosing a purification system is determining which of these issues you’re facing. Take into account the filter’s efficiency rating as well. The best of these will be rated according to the size of the particles being captured in microns. A filter that captures down to 0.3 microns is considered excellent. Remember to consider the noise level and the warranty as well. The most reputable manufacturers will supply a five year warranty and a machine that operates without any noise at all.
