Pleated filters with larger filtration surface area can thus achieve greater efficiency and last longer. Disposable filters, in turn, are easy to handle and the maintenance required is minimal. On the other hand, washable filters, when cleaned and reused, can be a green option.

Carbon filters are another good option for filtering bad-smelling odors and catching harmful gases, which in turn make the home airy and fresher.
