WE CLAIM:

1. A nasal-filter apparatus (100) comprising:

a pair of housings (110), wherein a distal end (115) of corresponding pair of housings (110) is open and a proximal end (120) of the corresponding pair of housings (110) comprises at least two rims (130);

at least two retainers (150) adapted to be placed inside the corresponding pair of housings (110) wherein the at least two retainers (150) together with the at least two rims (130) are configured to increase air flow;

at least two filters (160) placed inside the corresponding pair of housings (110) between corresponding at least two rims (130) and corresponding to the at least two retainers (150), wherein the at least two filters (160) are configured to restrict one or more pollutants present in the air from entering nostrils; and

a plurality of wings (170) placed on an outer periphery of the pair of housings (110), wherein the plurality of wings (170) are configured to provide grip inside the nasal cavity and prevents accidental ejection.

2. The apparatus (100) as claimed in claim 1, wherein the pair of housings (110) are fabricated using a medical graded thermo plastic material.

3. The apparatus (100) as claimed in claim 1, wherein a variation of the pair of housings (110) are designed to substantially match a shape of an inner surface of the nostrils of a user.

4. The apparatus (100) as claimed in claim 1, wherein an inner periphery of the pair of housings (110) comprises a plurality of flanges (140), wherein the plurality of flanges (140) are configured to hold the at least two retainers (150).

5. The apparatus (100) as claimed in claim 1, wherein the plurality of wings (170) comprises a plurality of collapsible wings which are tilted and pointed outside and collapses during insertion and expands during removal.

6. The apparatus (100) as claimed in claim 1, wherein the outer periphery of the pair of housings (110) towards the proximal end (120) comprises a tread pattern (175) configured to provide extra grip inside the nasal cavity and prevents accidental ejection.

7. The apparatus (100) as claimed in claim 1, wherein each of the at least two retainers (150) and the at least two rims (130) comprises one or more lines and the one or more lines are connected in a shape of triangle to provide strength and increase air flow.

8. The apparatus (100) as claimed in claim 1, wherein the at least two filters (160) are fabricated using nanofiber material, microfiber material or non- woven fabric.

9. The apparatus (100) as claimed in claim 1, wherein each of the at least two filters (160) comprises a replaceable filter.

10. The apparatus (100) as claimed in claim 1, further comprising a connector (180) mechanically coupled to a first side of each of the at least two housings (110).

11. The apparatus (100) as claimed in claim 9, wherein the connector (180) comprises a bend corresponding to a nasal septum of the user, wherein the bend is configured to provide support with comfort when inserted into the nostrils.
