Task promptDesign an indoor air-quality and humidity-control system for a 12 m² bedroom study in Enfield with a 2.4 m ceiling, opening window, central heating and no air conditioning. I use the room for long study sessions and sleep, have no diagnosed respiratory condition and do not want medical advice. Use current UK guidance to define sensible ventilation, particulate and humidity criteria, then compare exactly nine current devices: three HEPA air purifiers, three compressor dehumidifiers and three monitors that measure at least temperature, relative humidity and one useful air-quality indicator. Start with DEFRA UK-AIR, Ofgem, official Meaco, Philips, Blueair, Airthings or equivalent manufacturer pages, and accessible UK retailers such as Argos and John Lewis. Replace any inaccessible or discontinued candidate with a same-category equivalent. Build Essential, Balanced and Premium complete systems with target caps of £300, £550 and £900. Each system must include one device from every category and be tested for a normal study day, a poor-outdoor-air day when window opening is limited, and a winter damp week. Use current standard delivered prices and the current Ofgem electricity unit-rate path when the task runs; show promotions separately. Exclude ozone-generating products and do not assume ionisation is acceptable unless it can be disabled. Recommend one system and a staged operating plan. Do not buy products, create accounts, register warranties or contact sellers.
