Jump to the full listHow this shopping list works
We have tested dozens of products and put together the minimum effective kit to fix a damp UK bedroom. The items work together — the hygrometer tells you how bad it is, the dehumidifier and window vac tackle moisture, the mould spray cleans what is there, and the curtains and draught strips prevent heat loss that causes condensation.
Buy them all or start with the first three. The hygrometer is non-negotiable: you cannot fix what you cannot measure, and guessing wastes money.
The complete shopping list
Thlevel Mini Digital Hygrometer 4-Pack
Four hygrometers for roughly the price of one premium unit — put one in each room and monitor your whole flat. Accurate to ±1°C, updates every 10 seconds, and shows a comfort level indicator. Compact enough to leave on a windowsill or bedside table without being noticeable.
Devola 12L Low Energy Dehumidifier (Which? Best Buy)
A Which? Best Buy award winner from a UK brand. Costs less than 5p per hour to run — one of the most energy-efficient compressor dehumidifiers available. Laundry drying mode, continuous drainage option, and dust filter. Covers rooms up to 30m².
CubeTECH CTWV2 Cordless Window Vac
The #2 best-selling window vacuum on Amazon UK at roughly half the price of the Kärcher. Rechargeable, comes with microfibre cloth and squeegee. Does 80% of the job at 50% of the cost — the right trade-off for a budget kit.
HG Mould Spray 500ml
A specialist Dutch cleaning brand — not a supermarket own-brand. HG sprays as a fine mist that clings to vertical surfaces like walls and ceilings, unlike foam sprays that run off. Kills mould on contact and works on tiles, silicone seals, grout, painted walls and window frames.
Tapel Foam Draft Excluder with 3M Adhesive (8m, 2 rolls)
The difference between this and cheap foam tape is the genuine 3M 9448 adhesive — engineered to bond at both low and high temperatures. UK winters make cheap glue fail on cold window frames. This stays put. Two rolls totalling 8 metres — enough for 2-3 windows.
PONY DANCE Triple-Weave Thermal Blackout Curtains (Grey, 46x54)
Triple-weave technology creates an insulating air pocket between the curtain and window glass. This raises the glass surface temperature, directly reducing condensation. OEKO-TEX Standard 100 certified — tested against 1,000+ harmful chemicals. Eyelet fitting suits standard UK curtain poles.
Dryzone Anti-Mould Paint Additive 100ml
Made by Safeguard Europe, a specialist UK damp-proofing company used by tradespeople. This 100ml concentrate converts 5 litres of any emulsion paint into mould-resistant paint for up to 5 years. You don't need to buy expensive anti-mould paint — just add this to whatever colour you already have.

What results to expect
After one week with this kit, most people see humidity drop from 70–80% to 50–60%. That is the difference between condensation streaming down windows and a dry pane in the morning.
Condensation reduces noticeably within a few days of running the dehumidifier and wiping or vacuuming windows each morning. The room stops smelling musty, and bedding feels fresher.
After treating mould with the spray and maintaining lower humidity for a month, it usually stops coming back. The draught strips and thermal curtains also make the room feel warmer, so you may find yourself turning the heating down a degree or two.
What this kit costs to run
Frequently asked questions
Will this work in a rented flat?
Yes, every product is removable and leaves no damage. The draught strip peels off, the curtains hang on a normal pole, the dehumidifier is freestanding, and the paint additive is mixed into a normal paint job your landlord would approve.
Do I really need all 7 products?
Start with Tier 1 and add as needed. The hygrometer tells you how much more you need. Many people fix their bedroom with just the first three, then add the dehumidifier when winter hits.
How long before I see results?
Humidity drops within hours of running a dehumidifier. Mould stops returning within 2–4 weeks if you maintain lower humidity. The draught strips and curtains make the room feel warmer immediately.
Can I use this list for other rooms?
Yes, the same principles apply to bathrooms and living rooms. A bathroom may need an extractor fan instead of curtains, but the hygrometer, dehumidifier, mould spray and window vac are universal.
