A powered room air purifier including a non-movable air filter holder. The room air purifier may include at least one guide ramp located at an upper end of the air filter holder. An air filter may be installed into the air filter holder by a combination of translational and rotational movement of the air filter.

Powered room air purifier with easy-loading air filter

A conformable, unframed pleated air filter, comprising a plurality of bridging filaments on at least one face of the pleated air filter.

Conformable pleated air filter with bridging filaments

A powered room air purifier with a visual indicator of air quality, the visual indicator including: a reflector that defines a forwardly-open-ended reflecting cavity and that includes at least one through-opening in a floor or ceiling of the reflector; at least one diffuser layer that covers the forward opening of the forward-open-ended reflecting cavity; and, at least one LED light source that is positioned within the at least one through-opening, the LED light source and the reflector being configured so that the LED light source is shielded from line-of-sight view along a forward-rearward axis of the powered room air purifier.

The present disclosure relates to air filters. More particularly, it relates to air filters including pleated filter media that can be uniformly expanded and contracted. In some embodiments, the air filters are adjustably sized air filter systems. In some embodiments, the air filters can be used in a window opening.

Uniformly expandable air filter

Computer-implemented systems and methods for estimating a replacement status of an HVAC air filter. Outdoor weather data (e.g., outdoor temperature information), is obtained. A Total Runtime Value of the HVAC system is determined based upon the obtained outdoor weather data. Finally, a replacement status of the air filter is estimated as a function of a comparison of the Total Runtime Value with a Baseline Value. By correlating air filter replacement status with an estimated runtime of the HVAC system, a credible predictor of air filter usage is provided. By estimating fan runtime based on easily-obtained outdoor weather data, the methods are readily implemented with any existing HVAC system and do not require installation of sensors or other mechanical or electrical components to the HVAC system.

Systems and methods for predicting HVAC filter change

An air filter media () including a pleated fibrous filtration web () with a first major side () that includes at least one sorbent-loaded area () in which sorbent particles () are present on a first major surface () of the pleated fibrous filtration web (), at least some of the sorbent particles () being post-pleat-deposited sorbent particles.

Air filter media with post-pleat-deposited sorbent particles

An air filter including a visually uniform filter life indicator (), the air filter () comprising: a conformable, unframed air filter media () that is installable on at least a portion of an upstream face () of a filter-support layer of an air-handling system, wherein the conformable, unframed air filter media comprises at least one passivated area () that provides a visually uniform filter life indicator of the air filter. Filter life indicators are used in order that aspects of the filtration performance of an air filter can be monitored.

Air filter with passivated filter life indicator

A nestable framed pleated air filter, including a non-self-supporting, compressible, pleated air filter media with a plurality of oppositely-facing pleats and with a plurality of upstream pleat tips and downstream pleat tips and downstream pleat valleys, the pleated air filter media further including a plurality of bridging filaments that are bonded to at least some of the upstream pleat tips. The filter includes a frame with sidewalls that are angled so that the framed pleated air filter is nestable.

Air filters are disclosed. The air filters include filtration media comprising a first surface () comprising a first region () proximate a first end () of the filtration media and a second region () proximate a second end () of the filtration media. The second region () is configured to provide a zone including either a densified zone of the filtration media or a support layer () adjacent to the filtration media. Also an air conditioning unit with the air filters is disclosed. And also a method of manufacturing the air filters is disclosed.

Air conditioner filter and method of manufacture

An air filter () comprises an air filter media () with a sorbent-free area () that provides a visual filter life indicator zone () and with a sorbent-loaded area () that provides a visual reference zone ().

Air filter with visual filter life indicator zone and sorbent-loaded visual reference zone

A frame assembly for releasably maintaining an air filter. In some embodiments, the frame assembly includes a thermoformed body integrally forming a base, opposing side walls, opposing end walls, and at least one closure sub-assembly. The frame assembly is configured to releasable retain an air filter relative to the base via the closure sub-assembly. In other embodiments, the frame assembly defines, in a flat state, foldable side and end panels at the perimeter edges of a central grid panel; the frame assembly can be transitioned to a final state for receiving an air filter by folding the panels. The frame assemblies of the present disclosure are re-usable, allowing a user to replace a 'used' air filter with a 'new' air filter.
