Humidifiers, air purifiers & dehumidifiers

Humidifiers, air purifiers and dehumidifiers in South Africa

Updated 4 November 2026

A humidifier in South Africa costs from about R 199 for a small USB model, and a dehumidifier for a damp room runs from about R 2,999 to R 9,249, according to listings found in November 2026. The quickest way to current prices for your room is a request on BlaBlaPrice, where the AI looks through local sellers' price lists and asks what you need before it shows offers.

Dry air or damp rooms: choose the right machine

A humidifier adds moisture to dry air and is chosen for dry air, skin irritation and breathing comfort. A dehumidifier removes moisture from damp rooms and helps prevent mould. Local comparisons we found put a humidifier at about R 700 to R 750 and a dehumidifier at about R 3,700 to R 4,300, so the two are not interchangeable, and a damp bathroom needs the second. Measure the room area in square metres before you choose the capacity.

Certificates and warranty to check

Some dehumidifiers and air purifiers carry the AFSA Seal of Approval from the Allergy Foundation of South Africa, which matters if you buy for an allergy sufferer. Warranty terms differ: one brand's terms we found give two years covering parts and labour, so ask whether labour is included before you pay. Some sellers also offer a money-back guarantee, and you should check its conditions in writing.

Season and delivery

November falls at the start of summer, which runs from December to February, and winter runs from June to August. Buy a dehumidifier before the damp months and a humidifier before the dry ones. Some retailers offer free express delivery within South Africa, but units of 25 litres and more are heavy, so ask whether delivery reaches Johannesburg, Pretoria, Durban, Cape Town or Gqeberha, and whether installation is included.

What to put in your request

Give the device type, the room area in square metres, the purpose (damp air, dry air, allergies or dust), the filter or technology you want, such as HEPA, the capacity in litres per day, the features you need, the make and model if you know them, whether you accept used goods, and your budget. Units are metric, so state litres and square metres in the request.
