Spear & Jackson 38065 Air Purifier with HEPA & Carbon Filters, Air Cleaner for Allergies, Pollen, Pets, Dust, Smokers; Ionizer & Timer Function

This is a great little product for the job, very compact and relatively quiet considering it has a fan blowing like an ordinary fan, so it has a dual use and should be ideal on summer hot nights doing two jobs in one, cooling and moving the air and also purifying it. The design is excellent and its features perfect at the price, including ionizing & only 22watts. The filters are also the cheapest to replace, so basically there is nothing really to dislike. Some have commented on its noise level, which I consider to be acceptable and as it has a night quiet mode setting, which is quite good, I do not envisage this being too much of an issue. It is a fan after all and no louder than a good laptop or PC fan, slightly lower I would say, hence this may give buyers an example of the noise level. I can certainly recommend.

1. We are used to having fans or devices on which make a noise all day and overnight (listen to ambient sounds also) - so if you're not like that, this fan DOES make noise at sleep mode, but it's like a slow well built fan level of noise rather than a turbine! The noise makes it perfect for us.2. I bought this when we got our new dog - have lived with dogs for years, but wanted to make sure the house had a lower level of dust/dander etc.3. It seems to perform very well in our downstairs space and makes the space smell clean and crisp. I leave it on full mode with the ion option on. Time will tell if it reduces dirt and picks up airborne particles.4. HEPA filter and carbon filter easy to install but remember to open it up and remove the plastic covers! (Basically follow the instructions!)5. It hasn't overheated yet, nor appears warm to touch at all.6. Left it on overnight without any issues.7. The HEPA filter, the manual estimates, should last about 6 months - and there are apparently ways to clean these yourself.The long and short is that this probably does the job of a lot more expensive HEPA filters. I place the intake vent at the direction of the door so that any air coming into the room would be filtered (in theory anyway).I would say that the room feels less musty and dusty just from a couple of days use. Low power consumption also.

So I recently found out the newly acquired intense hacking is a kind of seasonal allergy. It seems to be nocturnal and every night I wheeze and cough, getting almost no sleep. Hence the reason for buying this.The double HEPA/carbon filter, sleep mode and 2 year guarantee were big selling points. I've used this for two weeks and I turn it on a half hour before going to bed. I make sure doors and windows are shut and have it in 'night mode'. I usually use it with the ioniser option on, to help purify the air. So it definitely has reduced my wheezing and coughing. The air feels cleaner and purer.But the noise.. this is not a quiet machine. I like white noise and have used an ioniser before, but this is much louder. I also found that setting the timer resulted in it waking me up when it bleeped loudly whilst turning itself off. (Why bleep?!) I was woken every single time. I now leave the timer off and it just runs all night.It has definitely helped my breathing and allows me to get much-needed sleep. But it certainly makes itself known..!Would recommend if you're not looking for a super quiet machine.. and if you're not expecting it to subtly knock itself off through the night. It is effective. My symptoms were extreme and relentless and it has absolutely helped me.

Edit: Nearly 2 years later, with daily use, my air purifier is still working really well. I change the filters every 4-6 months. I no longer need sinus treatments , and antihistamines and inhaler only at peak pollen times of the year. Still highly recommended; has been a health game-changer for me.——————————————————-I’ve had mine a month now, but noticed an improvement on the very first night I used it.I suffer with seasonal allergies that cause allergic asthma, requiring a recovery inhaler. I suspect house dust also affects me, particularly in my bedroom, despite thorough vacuuming and anti-allergen bedding. I would cough for a couple of hours when I laid down, whistle when I breathed and frequently needed my recovery inhaler before bed. I had to start the day with antihistamines as would start coughing as soon as I woke up. My sinuses were also always painful, I often had cold symptoms and I would often wake up in the night, coughing.The first night I used the air purifier, I noticed an immediate reduction in coughing. I don’t think with allergies you can really attribute that to a placibo effect. It has worked consistently since purchase, and on some days I don’t need antihistamines until I go out. I haven’t needed my sinus spray at all for the last couple of weeks. I use it before bed, and start it in the morning as I get up and get ready. It has made a huge different to both my health and my sleep quality.There are a few useful features: the sleep mode is acceptably quiet, producing a restful hum like white noise. The timer means you can set it to 1/2/4/8 hours and it reliably switches itself off. There is a negative ion function and different strengths of air flow. The only two criticisms I have of it are that it blows cool air, which is very pleasant in the warm weather but might need the unit to be positioned further away in the winter. Also, that the timer switches the appliance off with a beep, which might disturb very light sleepers.Unlike older reviews, the replacement filters are available and were easily purchased from the Silentnight Amazon store. Their price is acceptable for 6 months of use, making this a cost-effective way for allergy sufferers to improve their health, in my opinion.Based on my own experiences, I would highly recommend this product, and have in fact already recommended it to family members with seasonal allergies. It’s a fair price, has really worked for me and I would not hesitate buy it again should this one wear out.
