Delos Essentials Particle Air Filter
The Delos Essentials Particle Filter efficiently targets very small particles (3-10 micron) that can infiltrate the home from outdoors, or be caused by household dust, pollen, mould spores, smoke, dander and excrement produced by pets, pests and insects. Purifying air from these particles can help reduce threats to respiratory, heart, and lung health, and mitigate triggers for asthma, hay fever, and other respiratory allergies.
Delos Essentials Odour Air Filter
The Delos Essentials Odour Filter helps mitigate offensive odours and targets harmful organic pollutants that can be off-gassed by building materials, furniture, and finishings. Purifying air from such pollutants helps reduce the risk of headaches, nausea, and irritation to the eyes, nose, and throat.
