Excellent all-in-one purifier
I’m very happy with this Dyson Purifier Hot + Cool HP2 De-Nox. It works brilliantly as a purifier, heater and fan all in one unit. The air quality in my room noticeably improved within a short time, and it’s especially great for reducing odours and dust. The design looks premium, it’s easy to use, and the app control is very convenient. Heating is quick in winter and the cooling airflow is smooth and quiet. Overall, a high-quality product with excellent performance.

Q: Does the Dyson HP12 Purifier Hot + Cool De-Nox work like an air conditioner in summer?
A: No. The HP12 moves and circulates room air to create a cooling breeze, but it does not refrigerate the air like a split system or portable air conditioner. It is best for personal cooling and airflow, not for lowering room temperature in heatwaves.
Q: Can this Dyson heat the room while it is purifying the air?
A: Yes. The HP12 is designed to heat and purify at the same time, so it can warm the room while filtering airborne particles and some gases. That makes it more useful in winter than a purifier-only model that has no heating function.
Q: What does De-Nox mean on the Dyson HP12?
A: De-Nox refers to gas reduction aimed at nitrogen dioxide and similar pollutants from sources such as gas cooking or traffic drift. It is not the same as adding fragrance or masking odours, and it works alongside particle filtration rather than replacing it.
Q: Is the Dyson HP12 suitable if allergies are the main reason for buying it?
A: Yes, if the main concern is airborne dust, pollen and fine particles, this model is a suitable fit because it combines purification with year-round airflow. It is still important to keep doors and windows usage in mind, as open rooms can reduce purifier effectiveness.
Q: Can the Dyson HP12 replace a dehumidifier or remove damp from a room?
A: No. The HP12 is an air purifier, heater and fan, so it does not pull litres of moisture from the air like a dehumidifier. If condensation, mould or damp laundry drying is the main issue, a dedicated dehumidifier is usually the better match.
Q: Is this Dyson better for one room or for the whole home?
A: It is best treated as a single-room appliance rather than a whole-home solution. Purifiers like the HP12 work most effectively in the room they are placed in, so moving it between a bedroom and living area is more realistic than expecting house-wide coverage.
