Combined ionic air filter and humidifier apparatus
View Patent ↗A combined ionic air filter and humidifier apparatus filters air using ionic air filtering, humidifies at least a portion of the filtered ionized air, and directs the humidified filtered ionized air back into the environment. The apparatus generally includes an ionic air filter for ionizing and filtering air to produce filtered ionized air and a humidifier for humidifying the filtered ionized air to produce humidified filtered ionized air. A humidifier manifold fluidly couples the humidifier with the ionic air filter in a manner that does not allow the humidifier to interfere with operation of the ionic air filter. One or more fans draw the air into the ionic air filter and direct at least a portion of the filtered ionized air into the humidifier manifold such that the humidified filtered ionized air is discharged from the humidifier manifold.
1. A combined ionic air filter and humidifier apparatus comprising:
an electrical ionic air filter for ionizing air with electrically charged ions that attach to airborne particles and for removing charged particles from the ionized air to produce filtered ionized air;
a humidifier for generating moisture;
a humidifier manifold configured to mix the filtered ionized air produced by the ionic air filter with the moisture generated by the humidifier to produce humidified filtered ionized air, the humidifier manifold including a humidifier intake port fluidly coupled to the humidifier for receiving humidified air from the humidifier, a filter intake port fluidly coupled to the ionic air filter for separately receiving filtered ionized air from the ionic air filter, and a discharge port for discharging the humidified filtered ionized air; and
at least one fan for drawing air through the ionic air filter and directing at least a portion of the filtered ionized air into the filter intake port of the humidifier manifold such that the filtered ionized air mixes with moisture generated by the humidifier as air passes through the humidifier manifold.
2. The combined ionic air filter and humidifier apparatus of claim 1 wherein the ionic air filter includes an ionizer for ionizing air and a collector for collecting negatively charged particles in the ionized air.
3. The combined ionic air filter and humidifier apparatus of claim 2 wherein ionic air filter is a removable filter cartridge.
4. The combined ionic air filter and humidifier apparatus of claim 1 wherein the ionic air filter provides a Clean Air Delivery Rate (CADR) rating of at least 100.
5. The combined ionic air filter and humidifier apparatus of claim 1 wherein the at least one fan includes a plurality of fans and at least one of the fans is positioned to direct at least a portion of the filtered ionized air into the filter intake port.
6. The combined ionic air filter and humidifier apparatus of claim 5 wherein at least one of the fans is positioned to direct filtered ionized air around the humidifier manifold, and wherein the humidifier manifold has an elliptical cross-section.
7. The combined ionic air filter and humidifier apparatus of claim 5 further including a ducted cowling between the ionic air filter and at least one of the fans.
8. The combined ionic air filter and humidifier apparatus of claim 1 wherein the humidifier is an ultrasonic humidifier.
9. The combined ionic air filter and humidifier apparatus of claim 1 wherein the humidified intake port is located at one end of the humidifier manifold, the discharge port is located at another end of the humidifier manifold, and the filter intake port is located in a side of the humidifier manifold.
10. The combined ionic air filter and humidifier apparatus of claim 9 wherein the humidifier manifold includes a manifold wall extending from the filter intake port toward the humidifier intake port and configured to direct the filtered ionized air across the humidifier intake port before passing to the discharge port.
11. The combined ionic air filter and humidifier apparatus of claim 1 wherein the humidifier is located in a base, and wherein the ionic air filter, the at least one fan and the humidifier manifold are located in a housing extending from the base.
12. The combined ionic air filter and humidifier apparatus of claim 11 wherein the housing includes an intake side and a discharge side, wherein the ionic air filter is located proximate the intake side, wherein the humidifier manifold is located proximate the discharge side, and wherein the fan module is located between the ionic air filter and the humidifier manifold.
13. The combined ionic air filter and humidifier apparatus of claim 12 wherein the discharge port of the humidifier manifold is located on the discharge side of the body portion such that the humidified filtered ionized air is directed out of the discharge side.
14. The combined ionic air filter and humidifier apparatus of claim 12 wherein the housing includes a discharge grill covering the discharge side, and wherein the discharge port of the humidifier manifold is configured to pass at least partially through the discharge grill.
15. The combined ionic air filter and humidifier apparatus of claim 10 further including at least one removable water tank configured to be fluidly coupled to the base.
