Abstract

A device for filtering air, a rigid component comprising a transparent face shield, a fabric component, wherein the fabric component and the rigid component combine to cover an entire head of a user and form a seal around the user's neck, an intake port, an intake filter that filters intake air passing through the inlet port, an exhaust port, an exhaust filter that filters exhaust air passing through the outlet port, an air mover positioned to pull air through the exhaust port, whereby intake air is drawn into the device through the inlet port and whereby the intake air and exhaust air is filtered.

First claim

What is claimed is:

1 . A device for filtering air:
a rigid component comprising a transparent face shield; a fabric component, wherein the fabric component and the rigid component combine to cover an entire head of a user and form a seal around the user's neck; an intake port; an intake filter that filters intake air passing through the inlet port; an exhaust port; an exhaust filter that filters exhaust air passing through the outlet port; and an air mover positioned to pull air through the exhaust port, whereby intake air is drawn into the device through the inlet port and whereby the intake air and exhaust air is filtered.

2 . The device of claim 1 , wherein the rigid component further comprises a oval-shaped frame to which the transparent face shield is attached.

3 . The device of claim 2 , wherein the fabric component is releasably attached to the rigid component by stretching around the frame.

4 . The device of claim 1 , wherein the fabric component further comprises a drawstring to facilitate forming the seal around the neck of the user.

5 . The device of claim 1 , wherein a portion of the fabric component comprises that does not cover the rigid frame is substantially impermeable to air.

6 . The device of claim 5 , wherein another portion of the fabric component covers the air mover, and wherein the other portion of the fabric component is permeable to air.

7 . The device of claim 1 , wherein the fabric component has sufficient elasticity to allow the user to push the an outer surface of the fabric component to scratch or dab his face without breaking the seal around the neck.

8 . The device of claim 2 , wherein the air mover is attached to the frame.

9 . The device of claim 8 , wherein the air mover is a fan.

10 . The device of claim 9 , wherein the fan is attached with a vibration absorbing mount to reduce noise and vibration.

11 . The device of claim 1 , wherein the air mover comprises two fans that operate in parallel.

12 . The device of claim 1 , wherein the face shield is in the shape of a hemi-ellipsoid.

13 . The device of claim 2 , wherein the intake filter and the exhaust filter are housed within a single filter cartridge that is releasably attached to an inner surface of the frame so as to cover the intake port and the exhaust port.

14 . The device of claim 13 , wherein the filter cartridge is secured to the inner surface of the frame by a hook and loop fastener.

15 . The device of claim 13 , wherein the filter cartridge comprises a gasket that separates the intake port from the exhaust port.

16 . The device of claim 1 , wherein the combined surface areas of the intake and exhaust filters are greater than 200 inch 2 .

17 . The device of claim 1 , wherein the intake filter is adapted to block the passage of a virus, bacteria, smog, fungi, noxious gas, poisonous gas, smoke, or a combination thereof.

18 . The device of claim 1 , wherein the transparent face shield further comprises a hard coating to protect against abrasions and other damage.

19 . The device of claim 1 , further comprising an elastic band that connects to one side of the device, goes behind the head of the user inside of the fabric component, and connects to the other side of the device to better secure the device to the head of the user.

20 . The device of claim 2 , further comprising a controller mounted on the frame in communication with an app on a smart device for the user to monitor and control battery status and air flow.
