The right answer is HEPA filter.
A HEPA filter (High Efficiency on Particles Air) can filter up to 99.97% of 0.3μ aerial particles.
These filters are used to clean the air and retain suspended particles (dust, pollen, bacteria etc.) and other particles that can cause respiratory allergy in sensitive subjects.
They are very used in sterile rooms

Explanation:
The main arctic animals which will be affected by climate change are polar bears, seal, seabirds, and walrus.
Polar bears: Sea-ice cover at summer may be completely loss and this inhibits polar bears traveling from region to another to give birth — making the survival of mothers and cubs to be vulnerable.
Seal: Seal species are living mainly on ice and with the climate changing, ice cover also reduces — creating a not so comfortable environment for seal. They use sea ice as a feeding ground, birth place and a place where for raising their young, as well as for resting.
Seabirds (auks and gulls): They eat fishes and scavenge on top of sea ice, so when sea ice reduces so as their source of food and population.
Walrus: Uses sea ice as a feeding ground and source of food is on the sea floor while using sea ice as a diving platform. So any loss of sea ice cover, also affects their way of feeding and eventually, their population.
Overall, melting of ice affects salinity and temperature of surface waters, thereby affecting other marine life.
