We’ve got you covered

Suitable for the whole home and with an impressive throughput of 180m³/h the X-550 will help eradicate moisture where you need it most. Its fully portable design makes it to easy move around the house for added convenience.

Pro-ion Technology

Ions actively break down harmful particles, eliminating 99.9% of bacteria and viruses while naturally deodorising the air. The ioniser negatively charges micro particles causing them to destabilise and bind together. Pollutants and VOC’s such as smoke, viruses and odours become too heavy to remain airborne, safely removing them from your home with zero ozone.

No more laundry day blues

Dry your clothes inside, safely and quickly at the touch of a button. The X-550 dehumidifier with SafeDry Technology can accelerate the natural drying cycle, help avoid damage caused by the heat of a tumble dryer and reduce the bleaching caused by the sun. Perfect for delicate, and hard-wearing fabrics alike, keep your clothes like new for longer.

Save on a rainy day (and every day)

Save ENERGY, MONEY, TIME, and DAMAGE. Save up to 93% of the cost of using a tumble dryer as well as lower energy consumption. With running costs as low as 6p per hour it is affordable to use. A dehumidifier saves time compared to drying clothes naturally and saves damage caused by excess moisture levels. Help save the planet too; we use CFC free environmentally safe R290 gas and plant a tree for every unit sold.

Healthy home, healthy you

Preventing the hidden dangers of mould

Create a healthy environment and protect against mould, mildew, damp, and condensation. By improving the indoor air quality, you can positively impact your health. Damp air is a breeding ground for dust mites and mould spores, both of which can cause respiratory problems and other health issues. Have dryer fresher air, reduced humidity and moisture levels and help tackle musty and stale odours.

One touch convenience

Easy to use and packed full of features, the X-550 gives you so much. The one touch control panel is easy to use and makes the operation and functionality simple. Turn on, sit back and relax. Once the large 4.5L tank is full, the device has an auto shut off function. Simply empty and go again. For added convenience it also has a continuous drainage feature for longer use times.

Smarter by design

Aero-Dynamic Technology delivers market leading efficiency, the sensor intelligently adjusts the speed depending on the humidity, creating a consistently comfortable environment. Using only 0.26kW/h at whisper quiet 32dB, 30% quieter than previous models, the X-550 quietly and effectively reduces moisture levels in your home with a humidity range of 30-80%

Avalla X-200 smart large eco dehumidifier - 20l

X-550 Small, Powerful & Quiet

We brought 2 of these Dehumidifiers and were so pleased with how quiet they were. Our cats were very nervous with our last couple and wouldn't come downstairs when they were switched on but now it doesn't worry them.
They are very powerful and the perfect size for where we have put them.

Very happy with these purchases and would recommend happily buy again!

Sleek, Quiet and Compact

Having owned the X-200 for a few years and currently in the middle of renovations, we decided to opt for a replacement and Avalla was our first choice. Our model (X-550) seems to be a like-for-like replacement with the X-200 (20 litres a day) but is much quieter and sleeker looking (we can leave it running alongside our TV or in our bedroom without noticing). The humidistat on the unit also appears to be more accurate than our older model. The only downside is the cable seems about 15-20cm shorter, but this hasn't affected the performance in anyway.

Works like a charm

I'm really happy with my Avalla x200, it is a bit noisy to keep running at night but during the day it's great. After a couple of days of using it for 6-8 hrs a day the humidity has dropped greatly in my house.

Molto efficiente Avalla X-200 smart large eco dehumidifier - 20l

Ho un piano in casa che è per metà sotto il livello della strada e quindi ho un problema dell'umidità che penetra dal muro confinante con il sottosuolo.

Accendo questo deumidificatore durante la notte e la mattina trovo il recipiente pieno d'acqua.

L'umidità nell'ambiente si è abbassata notevolmente e l'aria è molto più leggera.

L'apparecchio in se è compatto, comodo da spostare con le ruote, design pulito, il display è di una facile comprensione.

Sono molto soddisfatta dell'acquisto e consiglio questo deumidificatore per gli ambienti medio grandi.
