Top critical review
Expected better attention to detail and quality from a Philips product
14 October 2015
I am writing this review after using the product for about 2.5 months. We had got this product mainly for our 5 year old son who suffers from allergic rhinitis. We use it regularly in our sons bed room. One main consideration that went into the decision of buying the filter was that it is one of the few filters available in the market which does not have an ioniser. We were unsure of the effect it has and were looking for a plain HEPA filter that filters fine dust.
The product comes with two filters a carbon fibre one and a HEPA filter. The carbon fibre one looks more like a plain coir mesh and the higher end models have better ones with proper frames. Both the filters do their jobs well but I am unsure whether it is enough as this one does not have an air quality indicator. The HEPA filter after 2.5 months usage looks messy.
My main complaint with the product is that the carbon fibre filter which is supposed to do the initial filtering is really flimsy, does not have a frame to hold it in place properly. It does not cover the HEPA filter completely as there are gaps in the outer edges and often sags/comes out of position when we move the filter around that I am forced to stick it in place with a tape. Due to this the load on the HEPA filter is more as the bigger dust particles and fibres (there are lot of it in our home) gets filtered in the HEPA layer rather than the carbon fibre filter. We cannot clean or vacuum the HEPA filter and thus will be forced to change it more frequently and HEPA filters are costly which we are supposed to change once in 1-2 years only. This is aggravated by the fact that the filter sucks in air though the edges and I feel if the air purifier had more vents in the front it will be much better. More over the higher end models have an additional pre-filter which I feel is mandatory in all air filters as it will filter out the bigger dust particles.
Refer the attached pictures. 1) Front side of a 2.5 month old HEPA filter, see the amount of fibre caught by it which should have been ideally caught by the carbon fibre filter. 2) Back side of HEPA filter. I am not sure how much dust escapes out of it and I feel that the HEPA filter is overloaded unnecessarily 3) The sagging flimsy Carbon fibre filter which creates a gap between it and HEPA filter. 4) Close up of the gap which you can see is huge which leads to an over load on the HEPA filter.
At the end of the day I am unsure whether the filter is adequate enough and feel that its not a value for money product. Expected better attention to detail and quality from a Philips product.
