I only leave it on when I'm in the house, so probably about 5 hours during the day and all throughout the night, and that seems to help. I have one in my living room and the other in my bedroom so for their roughly 15m² size I should be getting at least 5 air changes an hour. Therefore, the filter of the HoMedics air purifier is either only a HEPA-type filter (so not an actual HEPA filter) or alternatively the air purifier is not leakage free. As I am unable to carry much weigh I find this item easy to hold, and have no difficulty moving it around the room.

This would result in the filter being less effective and letting pollution pass through it before blowing it back into your environment. And since there might be little circulation, an air purifier could be an important part of keeping your home clean. My breathing had improved, and I could even 'taste' the air being a little cleaner and without the taste of dog I have become accustomed to. Keep the air at home clean and allergen free with the Homedics AR-10A-GB Professional HEPA Home Air Purifier . I have it on the lowest setting during the night, which provides a nourishing, humming background noise which carries me off in to my sleep.With 3 speeds, a Night mode for uninterrupted use whilst you sleep and Replace Filter Indicators, you can rely on the 5 component parts within the purifier to leave you with a cleaner and fresher smelling home. The HoMedics Professional HEPA air purifiers are primarily advertised towards people suffering with allergy. com Limited, registered in England and Wales with number 03934849, 27 Old Gloucester Street, London, WC1N 3AX, United Kingdom. We also did not like that the HoMedics Professional air purifier does not have any carbon filtration for removing odour, gas and chemical pollution (such as from cigarette smoke for example) from the air.

The AR-20-GB model has an airflow rate of 180m³/hr and the HoMedics Tower (AR-29-GB) air purifier has an airflow rate of 215m³/hr. One reason is that the suction from the vacuum cleaner will very likely damage the integrity of the filter media.

I received this machine with hesitation but upon opening it, and seeing that it is not big at all, I was relieved. The only negatives I can think of, and they have been mentioned by previous reviews, is the fact is has no handle so is semi-awkward to carry up the stairs each evening, and also the blue light that emits from the power button (I place a small pillow over it during the night). The HoMedics professional "HEPA air purifier" uses two filters: a pre-filter which is washable and a mechanical HEPA-type filter. The carbon odour filter removes common household smells from the home, like cooking and pet odours and smoke for fresher air.

The third, the actual top of the control panel was marked but I am assuming the plastic sheet can be removed and is just additional protection whilst in transit. The unit has three basic functions; an on/off button, a filter life indicator and a dial for the three different speed settings. A HEPA filter increases the filter lifespan by up to 5 times, reducing the amount you pay in the long run for clean air. So, my advice to you is go ahead and make the purchase if you are suffering from dog allergies and want a quick remedy.I find the highest level (3) to be just slightly too loud to watch TV with, so I opt for the 2nd level during the day. The company sells various products such as back, foot, and neck massagers, foot baths and humidifiers. The unit is basic and only offers three options: the power on/off button, clean filter indicator and the speed settings. i and my wife were totally impressed and amazed at the difference, so the UV system had worked and the oscillating tower had ensured that all area,s had been rectified. The right hand one on my unit barely latches such that it pops apart very easily causing the cast to open at the top right side if the unit is moved or knocked.
