This project was motivated by my interactions with healthcare workers who wanted to know where I got my CleanSpace Halo. Many abandoned their baggy blues when they failed to prevent SARS-Co-22 infections on the basis that “masks don’t work”. I invariably explain that gappy baggy blues let air in, hence airborne infections & that snug fitting ffp2/3 respirators do work. However, other medics failed fit tests (small faces, beards), caught covid & gave up on masking. So, for those who don’t get a good fit with an ffp respirator & those who can’t live without showing their toothy smiles, PAPRs seem to have appeal. Apart from the cost that is, so I’ve negotiated discount codes on the PAPRs, as well as the Far-UV & HEPAs cited below.

Disclaimer: I acknowledge, up front, the privilege involved in being able to afford this tech. Two members of my family get a good fit with their 3m ffp3 auras, swear by their efficacy & that’s their preferred mask.
This is an account of my experiences of clean air tech. I’m not going to go into technical details here because I’m not an engineer or tech expert (I therefore won't reply to technical questions). I recommend that anyone interested in procuring any of the items reviewed below do your own research. Having done mine and, based on mine & my family’s needs & requirements, I invested in the items cited below.
Full disclosure: I asked CleanSpace for a discount (we didn’t have wads of cash growing up, my mam always haggled, it rubbed off). They said they don’t do discounts but offered me one for free. I accepted (gratefully) on condition that it wasn’t contingent on a favourable/any review. I bought our Halos 14 months ago & CleanSpace never contacted me, at all. This is an unsolicited review based on 14 months of use. CleanSpace recommended the UK retailer, Cires, to procure the other 2 halos & I’m chuffed to report that they’ve kindly offered my readers a better discount than I managed for myself🙏 Other retailers were also recommended by CleanSpace but Cires was by far the most reasonable price (much cheaper than buying direct). Customer service was also excellent.
The discount code rates on all of the tech cited below are the same or better than I negotiated for myself. I do not receive commission on any sales. One provider offered. I declined for obvious reasons.
Air Purifying Respirator (PAPR)
PAPRs work by blowing filtered purified air. If there’s a minor leak, the system compensates by blowing more air, harder. PAPRs are therefore really useful for people who fail ffp2/3 respirator fit tests. I have a small face & although I love the ffp3 Auras (my go to mask for outdoor gatherings), I don’t get a good seal & wouldn’t pass a fit test for high risk indoor situations, such as healthcare. As a result, I delayed critical healthcare checks, something I wasn’t comfortable with. Hence, my first PAPR purchase: The CleanSpace Halo
CleanSpace Halo: Reasons for buying/Pros
It’s compact, comfortable & although I sound a bit Darth Vaderish when I speak, I’ve been told it looks quite cool, in a high tech geeky kinda way. I style mine with the brightest clothes & bling in my repertoire, so the Halo looks like just another mad fashion accessory.
· Healthcare & routine checks are extremely important to maintain & although I always strive for the Swiss cheese (infection control protocol) when booking appointments, the first appointment of the day, for example, isn’t always possible & delaying appointments isn’t always advisable.
· It’s transparent so your face/smile is visible, which seems to be less trauma/denial inducing/triggering than white respirators in all situations. It looks like a medical apparatus, which, in my experience, garners more understanding & kinder reactions.
· We travel a lot in our campervan & are frequent ferry & Eurotunnel users. Since donning our Halo’s, immigration & customs can see our faces so there’s no need to pull masks down. We’ve never encountered any hostility with officials (even in auras).
· I highly recommend ordering a car charger to recharge on the move
· The CleanSpace pro reportedly has a longer battery life & comes with more bells & whistles. Others have complained of ongoing glitches (including randomly cutting out for a few seconds) associated with the pro but not the Halo, which is why I opted for the Halo. If you’re in the market for a CleanSpace, it’s worth checking if the glitches in the pro have been ironed out
· Cons:
· The Halo’s battery life is estimated to be up to 8 hours, though I’ve never worn it for that long. There’s no replacement battery but a car charger allows recharging on the go.
· The filter is at the back of the neck so lying down for prolonged periods (e.g hospital admission) would prevent airflow.
I was incredibly impressed with Cires customer services & speed of delivery. They have very generously offered readers a 10% discount (I only managed 5% for myself) on a very fair price🙏: https://www.cires-safe.com/product-page/cleanspace-halo-powered-respirator

3m Versaflo
Reasons for buying/Pros


· The 3m Versaflo is a hooded PAPR with battery life up to 12 hours (9-12). Not only does it have a longer battery life, you can replace the battery with a spare for continuous use. I bought one Versaflo to have in case of a medical emergency, to cover long waiting times. I bought the large hood to fit all of us. I expected it to be a bit big on me but it fits just fine.
· Hospital admission: In the event of any family member being admitted to hospital, the hooded PAPR is more comfortable for continuous ongoing use.
· The filter can be moved to the front making lying down/being reclined (hospital admission) possible, though care would have to be taken with hose.
· People who own & use their Versaflo tell me it’s possible to use a straw without compromising safety. The positive air pressure boots up & blows out air to compensate. Useful in A&E/ED, needing to stay hydrated.
· Dental hacks: lift to just below nose so the purified air blows into the face
I know someone who bought a small hood & uses it with their immunocompromised toddler, too young to mask, when accessing healthcare. She dresses her up like an astronaut – making it into an adventure
If you can't live without lippy & teethy smiles, this bad boy is for you👇
Cons:
· Attention grabber. You won’t fade into the background in this but if I’m sick enough to be in need of emergency healthcare, spending hours in over crowded, under ventilated health care settings with unmasked peeps, I won’t be giving a flying feck what anyone thinks of me.
· I bought mine from the facemask store @20% discount & have secured the same discount for readers. Since buying mine a few weeks ago, cheaper options are now available:

Far-UV: Sterilray Sabre "May the force be with you"👊

From the Sterilray website: “There are now dozens of studies that have proven the efficacy and safety of Far-UV Sterilray”: https://sterilray.com/
I love love love my Sabre. Together with my Darth Vader-y Halo, I feel like a Starwars extra! Given my family’s lifestyle, which involves a lot of travel & using holiday rentals, the Sabre cuts airing time considerably. Innovative tech like this, lacking investment for production at scale, is expensive to manufacture & produce but it makes my life a lot easier & safer so for that, the investment was worth every penny.
The Sabre doesn’t just clean the air, it disinfects surfaces too. I view it as a much more efficient, effective, economical & an environmentally friendly solution versus wiping surfaces down with sprays/wipes. I also use it to zap fresh produce that doesn’t come wrapped, in addition to rinsing with water.
From a recent paper: “Far-UVC lamps are a highly cost-effective solution for societies during normal winter and pandemic scenarios. Implementation in the settings studied should be considered as a safe and effective measure for infectious disease control”

HEPA Filters (high efficiency particle arresting energy filters)
Smart Air all the way

I absolutely love my Sqair, Smart Air HEPA filter, which has been a trusted companion for over two years. We bought it for it's portability, i.e. fits snugly on the bunkbed in the camper. The legs unscrew so it can be stored like a box. We also have 3QT hand held HEPA filters which we used before buying PAPRs for healthcare appointments. They consistently outperform generic brands in performance tests.
Staying in holiday lets, my Sqair gets to work while I make my way round with the Sabre. The 3QTs are very handy airing bathrooms with no windows. Pre-charge with a USB cable & they're good to go or attach to a power pack.
Friends also pop the 3QT's in their kids' back pack to put on their desks at school & I know a lot of academics & office workers who do the same. Another common use is on public transport, including buses and planes.
The SA600 is perfect for larger spaces & absolutely should be a regular feature in schools & healthcare settings.
See my recent article below re importance of HEPA filters in schools & healthcare, drawing on research proving the efficacy of HEPA filters, alongside ventilation and masks. On 29 April, a study documented what happened when air purifiers were placed in 95 randomly chosen classrooms across 5 schools in Milan. The results show that the air purifiers reduced indoor air pollution 28%, corresponding with 11% reduction in student absences.
Parents, teachers, head teachers, healthcare managers & workers: Now's your chance to get a discounted SA600 for your classroom, wards, clinics. Obvs, anyone sharing air with others would be wise to get either the Sqair or the SA600. See discount details👇
Smart Air technology is top notch & they're lovely people to deal with. They're heavily invested in clean air education & community advocacy. Their sustainability, & that of the other brilliant innovators cited here, relies on our support for their sustainability.
