Supportive home health devices, weighed up honestly
Nebulisers, daylight lamps, air purifiers and TENS units are everywhere online — but the marketing rarely matches the evidence. We cut through the lux numbers, HEPA grades and NICE guidance so you can decide what's genuinely worth it for your home. Educational only — for personal decisions, speak to your GP or pharmacist.
Why this category needs a watchdog
Home-care devices sit in an awkward gap. They are sold as consumer gadgets, yet they touch real conditions — breathlessness, low winter mood, indoor air quality, persistent pain. That mix invites overclaiming: a £20 lamp branded "SAD therapy" that never reaches 10,000 lux; an "antibacterial HEPA" purifier whose filter isn't actually H13; a nebuliser sold for asthma when the NHS would steer you to a reliever inhaler and spacer instead.
Our job is to separate the device categories that have a clear, evidence-led use from those where the science is thinner than the packaging suggests — and to tell you the difference plainly. We never sell these products and we never name brands. We review the category and the criteria that matter, so you can shop with your eyes open.
The four home-care hubs
Each guide explains what the device does, what the UK evidence actually says, and the specifications worth checking before you buy.
Nebulisers & saline therapy
For loosening stubborn phlegm in conditions like bronchiectasis. We explain why the NHS rarely recommends a home nebuliser for asthma or routine COPD — and when one genuinely helps.
Read the guide HUBSAD & daylight lamps
Around 2 million people in the UK get seasonal affective disorder. We cover the 10,000-lux standard, UV-free output, the UKCA/CE mark to check for, and what light therapy can and can't do.
Read the guide HUBAir purifiers & water filtration
Cutting through 'HEPA-type' marketing to the real EN 1822 grades. Most people spend most of their time indoors — we explain when a true-HEPA unit is worth it and when it isn't.
Read the guide HUBTENS units & pain support
How the pain-gate mechanism works, what high- vs low-frequency settings do, and the honest position: NICE does not recommend TENS for chronic primary pain, though many people still find it eases symptoms.

Five checks that apply across all four categories — they weed out most of the overclaiming.
A UKCA or CE mark
For anything making a health claim, look for the conformity mark. A SAD lamp, for instance, should be UV-free and UKCA/CE marked; absence is a red flag.
The real specification, not the buzzword
"True HEPA" / H13 means 99.95% capture at 0.3 microns under EN 1822. "HEPA-type" or "HEPA-like" is not the same thing. Demand the grade, not the label.
Evidence that matches the claim
Check what the NHS, NICE or MHRA actually say about the category — not just the product page. We summarise this in each hub guide.
Running and replacement costs
Filters, electrodes and consumables add up. A cheap unit with pricey, frequent replacements can cost more over a year than a dearer one.
Whether you need a clinician first
Nebuliser drugs are prescription-led; some conditions need a GP's plan. Signposting to professional advice is part of using these devices safely.
A device is not a diagnosis. Home-care tools support care that's already been talked through with a professional — they don't replace it. Persistent breathlessness, low mood, new pain or worsening symptoms should be discussed with your GP, pharmacist or the NHS, who can also tell you when something is available on prescription rather than worth buying yourself.
A genuinely mixed bag. Daylight lamps and true-HEPA air purifiers have a clear, evidence-supported use for the right person — provided you buy on specification, not marketing. Home nebulisers and TENS units are far more situational: useful for some, but routinely over-sold for conditions where the NHS or NICE would point you elsewhere. Read the category guide before you spend.
People matching a device to a specific, clinician-discussed need — and checking the spec (lux, HEPA grade, conformity mark) rather than the headline claim.
"Medical-grade" language with no certification, lamps that never hit 10,000 lux, "HEPA-type" filters, and nebulisers or TENS units sold as cure-alls.
Common questions about home-care devices
Are these devices available on the NHS?
Sometimes. A consultant may arrange a home nebuliser in specific circumstances, for example, but light therapy is generally not available on the NHS as the evidence is considered inconclusive. Ask your GP or pharmacist what applies to your situation before buying privately.
Is a more expensive device always better?
No. What matters is the specification meeting a recognised standard — 10,000 lux and UV-free for a SAD lamp, H13/EN 1822 for a true-HEPA purifier. A mid-priced unit that meets the standard beats a premium one that only hints at it.
Do you recommend specific brands?
Never. We're independent, take no commission and name no products. Each hub guide reviews the category and the criteria, so you can apply them to whatever's on the shelf.
Can a home device treat my condition?
These are supportive tools, not treatments. They work best alongside care discussed with a professional. For any personal health decision, speak to your GP, pharmacist or the NHS.
