Abstract

An air purifier may have a casing defining a support to receive a substrate of a plant, an artificial plant and/or a removable pot. The casing forms a chamber, an outer wall of the casing defining one or more air inlets, and one or more air outlets. An air filter(s) is housed in the chamber. A fan os housed within the chamber. A motor is operable to drive the fan, whereby the fan is operable to draw in air through one or more air inlets in the casing and through the air filter, the fan further operable to expel the drawn-in air through the one or more air outlets in the casing.

Claims (39)

1 . A method for replacing an air filter in an air purifier, the method comprising:

opening a lower casing portion of the air purifier to gain access to the air filter by removing a base of the lower casing portion to gain access to a filter chamber of the air purifier;

disengaging an annular cover of the air filter from an annular filter support, the annular cover being at an end of a first panel of porous material in a sleeve shape, the first panel of porous material of the air filter adapted to be used as a filter;

removing the first panel of porous material from the annular filter support of the air purifier; and

mounting a second panel of porous material onto the annular filter support.

2 . The method according to claim 1 , wherein removing the base from the lower casing portion includes unscrewing the base from the lower casing portion.

3 . The method according to claim 1 , wherein disengaging the annular cover includes unclipping the annular cover from the annular filter support.

4 . The method according to claim 1 , further comprising engaging the annular cover of the air filter with an end of the second panel after mounting the second panel onto the annular filter support.

5 . The method according to claim 1 , further comprising causing the second panel to unfold from a native collapsed state to a filtering state, the second panel in the filtering state having a tubular shape.

6 . The method according to claim 5 , wherein causing the second panel to unfold from the native collapsed state to the filtering state includes stretching the second panel to fit onto the annular filter support.

7 . The method according to claim 1 , wherein removing the base includes extracting the annular filter support from the filter chamber from an underside of the air purifier.

8 . The method according to claim 1 , wherein removing the base includes disengaging the annular cover of the air filter from a bottom wall of an upper casing portion, the bottom wall delimiting the filter chamber from a fan chamber of the upper casing portion.

9 . The method according to claim 8 , wherein disengaging the annular cover from the bottom wall includes unsealing an air passageway from the fan chamber to a central air plenum of the air filter.

10 . The method according to claim 2 , wherein unscrewing the base from the lower casing portion includes manually unscrewing the base via a handle.

11 . The method according to claim 1 , wherein mounting the second panel includes positioning an inner surface of the second panel against the annular filter support.

12 . The method according to claim 11 , wherein positioning the inner surface of the second panel against the annular filter support includes causing the second panel to adopt a tubular shape onto the annular filter support.

13 . The method according to claim 1 , wherein mounting the second panel onto the annular filter support includes seating an end of the second panel onto a top face of a removable base of the lower casing portion, the annular filter support being part of the base.

14 . The method according to claim 1 , further comprising engaging the annular cover of the air filter with an end of the second panel of porous material after having disengaged the annular cover from the annular filter support.

15 . The method according to claim 1 , further comprising aligning a central axis of the air filter having the second panel of porous material and the annular filter support with a central axis of the air purifier.

16 . A method for replacing an air filter in an air purifier, the method comprising:

opening a lower casing portion of the air purifier to gain access to the air filter by removing a base of the lower casing portion to gain access to a filter chamber of the air purifier;

disengaging an annular cover of the air filter from an annular filter support, the annular cover being at an end of a first panel of porous material in a sleeve shape, the first panel of porous material of the air filter adapted to be used as a filter;

removing the first panel of porous material from the annular filter support of the air purifier; and

mounting a second panel of porous material onto the annular filter support by seating an end of the second panel onto a top face of a removable base of the lower casing portion, the annular filter support being part of the base.

17 . The method according to claim 16 , wherein removing the base from the lower casing portion includes unscrewing the base from the lower casing portion.

18 . The method according to claim 16 , wherein disengaging the annular cover includes unclipping the annular cover from the annular filter support.

19 . The method according to claim 16 , further comprising engaging the annular cover of the air filter with an end of the second panel after mounting the second panel onto the annular filter support.

20 . The method according to claim 16 , further comprising causing the second panel to unfold from a native collapsed state to a filtering state, the second panel in the filtering state having a tubular shape.

21 . The method according to claim 20 , wherein causing the second panel to unfold from the native collapsed state to the filtering state includes stretching the second panel to fit onto the annular filter support.

22 . The method according to claim 16 , wherein removing the base includes extracting the annular filter support from the filter chamber from an underside of the air purifier.

23 . The method according to claim 16 , wherein removing the base includes disengaging the annular cover of the air filter from a bottom wall of an upper casing portion, the bottom wall delimiting the filter chamber from a fan chamber of the upper casing portion.

24 . The method according to claim 23 , wherein disengaging the annular cover from the bottom wall includes unsealing an air passageway from the fan chamber to a central air plenum of the air filter.

25 . The method according to claim 17 , wherein unscrewing the base from the lower casing portion includes manually unscrewing the base via a handle.

26 . The method according to claim 16 , wherein mounting the second panel includes positioning an inner surface of the second panel against the annular filter support.

27 . The method according to claim 26 , wherein positioning the inner surface of the second panel against the annular filter support includes causing the second panel to adopt a tubular shape onto the annular filter support.

28 . The method according to claim 16 , further comprising engaging the annular cover of the air filter with an end of the second panel of porous material after having disengaged the annular cover from the annular filter support.

29 . The method according to claim 16 , further comprising aligning a central axis of the air filter having the second panel of porous material and the annular filter support with a central axis of the air purifier.

30 . The method according to claim 16 , further comprising removing a plant pot from a top of the air purifier prior to opening the lower casing portion.

31 . The method according to claim 1 , further comprising removing a plant pot from a top of the air purifier prior to opening the lower casing portion.
