Fast performance. Quiet power. Real-time results. The Shark Air Purifier 4 removes allergens, mould, bacteria and other particles from your air, with 4 powerful fans and intelligent air quality monitoring - for all-day clean air confidence.
4-Fan Technology
4 powerful air purifier fans efficiently clean air and quickly circulates it throughout the room. Auto mode adjusts the fan speed automatically to keep your air quality level optimum, or you can manually switch between speed settings with the touchscreen or remote control.
Clean Sense IQ
Built-in sensors intelligently detect and track your home's air quality. Cleaning power is automatically adjusted until air quality is 100% cleaned. Results are reported in real time for all-day clean air confidence. When your air quality reaches 100%, the fans will go into power saving standby mode.
Display Screen
Easily toggle between real-time information including percentage (%) of clean air, air quality level (GOOD, FAIR or POOR), the amount of particulate matter (PM) that is in your air, and estimated time remaining until your air is fully cleaned. Choose from 3 display screen brightness levels including a 'screen off' setting, perfect for overnight use.
Multi-staged filtration
The Shark filter removes odours, captures 99.97% of pollutants and allergens at 0.3 microns, and traps dirt, dander and particles. A carbon layer within the filter removes and neutralises odours, such as those caused by pets or cooking. The display screen also clearly shows time remaining until the filter needs replacing. No need to wash the filters.

sorted byBuy a air purifier that has a high ‘Clean Air Delivery Rate’ measured in m³/h. The higher the better.
Get one that has a HEPA filter.
Get one that has a air quality sensor that you can leave on ‘AUTO’ and let it just run when it detects high levels of PM2.5, the stuff that is bad for your health.
For me, this Shark doesn’t tick any of those boxes.
I have one
Gets rid smells. Quiet. Excellent at detecting bad air quality. If dog walks past it immediately goes in high mode.
No gimmicks just does what's required. Filter very easy to clean.
i have some xiaomi ones, and i've never changed the filters on them, get a warning on the display to say change them as they work on rfid but just ignore and it works as normal
I also suffer from hay-fever in the summer.
What would you recommend?
It’s not going to be a miracle, you will still need to dust surfaces.
Will be buying a dehumidifier as some damp appearing inside one bedroom and bathroom (roof will be changed next year once weather better). Can these work in conjunction?
It’s not going to do much for your damp problem though. Fixing the roof and getting a dehumidifier would be a priority if it were me.
I bought its bigger brother HE600UK and received the delivery today. The size is HUGE. It is the same height as a 60L bin. I did not expect that. Despite that, it looks very good, modern and sleek. The touchscreen buttons and everything make it feel as a premium product. I am going to keep it.
Used in the kitchen for 1 hour now, can already feel the air is fresher and the food smell is less stronger. I will continoue checking and hope it does wonders.

I posted that here a while ago hotukdeals.com/dea…465
My friend suffers from severe asthma and got one from the links below for his home. He said that it made so much difference that he got the second one soon after, so he wouldn't have to move it between the rooms. So I then got one myself, especially after reading that it uses the only NASA certified air purifying technology... I mainly use it when hoovering the house, and occasionally I switch on the ozone function as well. Other than that, I can't see much difference myself. But I don't have hayfever or asthma...
First link is the cheapest option I've found in the UK, and the last link is the cheapest option in the US.

My flat gathers a lot of dust as I’m close to a busy road. Even with the windows closed, I get a lot of dust so hoping this goes a long way to getting rid of some of the dust.

set it to auto and let it ramp up / idle when needed
No, but this air purifier features a high quality filter that captures 99.97% of particles 0.3 microns or larger.
it’s not a miracle worker that will eradicate the smells of a curry or pungent dish immediately.
I made a katsu curry last night and this morning you can’t really smell it if at all. Last night afterwards you could still smell that we had made katsu curry.
