Finding the right vornado air purifier filter replacement comes down to matching your purifier cabinet size with the correct media pack. If you run a console model like the AC300, AC500, or PCO series, you need the large rectangular MD1-0022 true HEPA element paired with an MD1-0023 carbon pre-filter wrap. Compact desktop units like the CYLO50 or QUBE50 require the square slide-in MD1-0039 cartridge instead. Choosing an incompatible shape or thickness prevents the door latch from closing and breaks the airtight perimeter seal required for effective room cleaning.

This guide covers 5 replacement packs designed to maintain consistent airflow and capture fine particulate matter across various machine generations. They differ primarily in machine compatibility, filter staging, and the length of time the bundled components support your maintenance cycle. Some provide a full two-year multi-stage supply for large consoles, another is tailored for a single-year refresh cycle, and dedicated options serve compact cylinder units. Checking your machine model number against the appropriate cartridge geometry avoids fitment issues and keeps fan motor resistance within design specifications, much like planning a levoit air purifier filter replacement schedule for other household rooms.

Best for
Large consoles needing complete two-year supplies

Pros

Two H13 HEPA cores included
Four carbon pre-filter sheets
MERV 13 rated efficiency

Cons

Incompatible with CYLO models

The MD1-0022 Replacement Filter pack is an all-in-one six-piece replenishment kit configured to keep full-sized console purifiers running at full efficiency. It includes two H13 true HEPA filters and four activated carbon pre-filters, creating a multi-stage barrier against particulate and gaseous irritants. The primary pleated elements measure 11.8 inches long by 10.2 inches wide with a 1-inch thickness, engineered to slide directly into the rear filter tracks of full-sized units without buckling the frame.

This kit is built for households that operate their air cleaner continuously throughout the year. The pairing of two main filters and four carbon sheets maps precisely to standard usage guidelines, where the carbon wrap is swapped every three months and the true HEPA core is changed every twelve months. This configuration provides a complete two-year supply for single-filter machines or a full one-year overhaul for dual-filter chassis models like the AC500 and PCO500 series. If your unit is located near kitchens or pets, the frequent carbon swaps protect the dense HEPA pleats from premature dust loading.

It is fully compatible with Vornado air purifier models AC300, AC350, AC500, AC550, PCO200, PCO300, PCO375DC, PCO500, and PCO575DC. Owners of compact models like the CYLO or QUBE series will need to look elsewhere, as this rectangular frame is specifically designed for standard cabinet bays.

Includes two H13 true HEPA filters and four activated carbon pre-filters.
Measures 11.8 inches by 10.2 inches by 1 inch for exact cabinet fitment.
Carries a MERV 13 rating to trap airborne particles down to 0.3 microns.
Engineered for AC300, AC350, AC500, AC550, and PCO air purifier platforms.

Best for
Everyday home spaces needing durable pleats

Pros

Sturdy polypropylene filter construction
Standardized left-to-right airflow fit
Full six-piece replacement bundle

Cons

Does not fit QUBE units

The MD1-0022 Filter for Vornado Air Purifier focuses on durable build quality for routine indoor air upkeep. This package also provides a six-piece set containing two primary particulate filters and four carbon stage sheets. Built with durable polypropylene media, the pleated main core holds its shape under continuous static pressure from high-velocity vortex blowers, preventing bypass air from slipping around unsealed edges.

This filter bundle suits busy living rooms, master bedrooms, and home workspaces that demand stable filtration performance without frequent frame collapse. The rectangular filters feature an airflow direction designed to move air from left to right through the media, ensuring proper graduated capture. Large debris stays embedded on the outer surface while microscopic particulates become trapped deep inside the pleated matrix, maintaining balanced motor airflow over prolonged operation.

Fitment covers the full family of larger cabinets, including the AC300, AC350, AC500, AC550, PCO200, PCO300, PCO375DC, PCO500, and PCO575DC. If you run smaller cylindrical desktop units, this set will not slide into your chamber, but for mid-to-large floor purifiers, it provides a solid multi-filter supply ready for scheduled changes.

Contains two main filters and four MD1-0023 carbon sheet layers.
Constructed from sturdy polypropylene pleated filtration material.
Designed for left-to-right airflow orientation inside standard housing bays.
Directly matches Vornado console air purifier model specifications.

Best for
Proactive owners who vacuum pre-filters monthly

Pros

H13 grade True HEPA media
Vacuum-cleanable monthly exterior surface
Broad AC and PCO fitment

Cons

Thick three-inch overall packaging

The PUREBURG Air Purifier Filter Compatible set is designed for users who take a proactive approach to equipment care. Offering two H13 true HEPA filters alongside four carbon pre-filter layers, this kit matches the standard MD1-0022 and MD1-0023 sizing. The manufacturer specifically notes that the filter core can be removed once a month and gently cleared with a soft brush or vacuum cleaner, helping extend media longevity in high-dust environments.

This set suits users who manage homes with shedding pets or seasonal pollen intrusions where rapid pre-filter loading is a routine problem. Regular external maintenance keeps airflow moving freely through the cabinet, similar to cleaning practices recommended when maintaining a blue air purifier filter in high-traffic living spaces. Remember to remove the protective plastic wrapping completely before placing the new inserts into your machine chamber to prevent airflow restriction.

The pack fits the AC300, AC350, AC500, AC550, PCO200, PCO300, PCO500, PCO375DC, and PCO575DC lines. While it gives way to single-cartridge kits if you only run a smaller bedroom unit, it serves owners of larger chassis models who want the flexibility of routine manual dusting between scheduled component retirements.

Supplies two H13 true HEPA cores and four carbon pre-filter elements.
Captures fine PM2.5 particles down to 0.3 microns and neutralizes odors.
Allows gentle monthly vacuuming or soft brushing to clear surface lint.
Installs by hand with no specialized tools or mounting brackets needed.

Best for
Single-filter AC console owners wanting annual kits

Pros

Dedicated one-year supply ratio
Four quarterly pre-filter changes
True MERV 13 fine capture

Cons

Includes only one HEPA filter

The Replacement Filter Combo is specifically packaged as a streamlined one-year maintenance set for a single air purifier. Unlike larger multi-HEPA bundles, this kit contains exactly one H13 grade MD1-0022 main filter and four MD1-0023 activated carbon pre-filters. This ratio provides four quarterly carbon wraps to handle coarse lint, pet hair, and cooking odors, paired with a single HEPA core rated for twelve full months of service.

This combination is tailored for owners of mid-sized machines such as the AC300 or AC350 that house a single filter core. Purchasing this exact set eliminates the clutter of storing surplus HEPA frames in closets where pleated media can absorb ambient moisture or gather ambient dust. The pleated structure holds a MERV 13 rating, delivering fine particle capture that reliably removes microscopic allergens throughout its one-year operating window.

The listing explicitly lists compatibility for the AC300, AC350, AC500, and AC550 platforms. Owners of dual-filter consoles like the AC500 should note that because this package contains only one HEPA element, you would need two separate packs to perform a simultaneous overhaul of both filter bays on those larger machines.

Complete one-year replacement cycle for single-bay air cleaners.
Includes one H13 main filter and four activated carbon pre-filters.
Carries an official MERV 13 air efficiency filtration rating.
Tailored specifically for AC300, AC350, AC500, and AC550 model lines.

MD1-0039 Filter

Best for
Owners of compact CYLO and QUBE units

Pros

Direct fit for CYLO and QUBE
Three-in-one integrated cartridge
Two complete cartridges included

Cons

Will not fit large AC consoles

The MD1-0039 Filter diverges completely from the large console formats, delivering a dedicated replacement for compact desktop and personal purifiers. This two-pack features an integrated three-in-one square cartridge design that combines an outer pre-filter, a main H13 particulate core, and an activated carbon layer inside a unified frame. Each cartridge measures 7.25 inches long by 7.25 inches wide with a 2.25-inch depth, matching the smaller internal footprints of compact devices.

This cartridge is ideal for shoppers running tabletop units in dorm rooms, home nurseries, or small personal office nooks. Because the pre-filter, HEPA layer, and carbon media are built into a single slide-in frame, changing the filter requires zero alignment of loose carbon wraps or secondary clips. This integrated design provides a simpler routine than the multi-layered filter setups found on legacy holmes air purifier filters, allowing for rapid slide-in swaps.

Compatibility is strictly limited to the CYLO and QUBE series, specifically fitting the CYLO50 (AC1-0044-43), CYLO51 (AC1-0045-07), and QUBE50 (AC1-0046-43). It will not fit large rectangular console units, but for compact machines, this two-pack supplies two full filtration cycles in one compact package.

Includes two complete three-stage integrated replacement cartridges.
Combines pre-filter, H13 main media, and activated carbon in one block.
Measures 7.25 inches square with a 2.25-inch slide-in thickness profile.
Designed specifically for CYLO50, CYLO51, and QUBE50 purifier housings.

Buying Tips for Vornado Air Purifier Filters

Before purchasing any replacement media, inspect the silver specification label located on the underside or rear panel of your machine cabinet. Vornado console models use precise part codes such as AC1-0015-06 for the AC300 or AC1-0018-06 for the PCO500. Knowing your exact model code confirms whether your machine requires the full-sized 11.8-inch rectangular MD1-0022 frame or the compact 7.25-inch square MD1-0039 cartridge. Ordering by cabinet appearance alone often leads to sizing mismatches, especially between mid-size consoles and compact desktop cubes.

Take note of how many active filter bays your unit operates. While models like the AC300, AC350, and PCO200 utilize a single HEPA element, larger high-capacity machines like the AC500 and PCO500 feature dual chambers that require two MD1-0022 filters and two MD1-0023 pre-filters installed simultaneously. If you operate an AC500, a six-piece bundle containing two HEPA cores will cover one complete machine refresh, whereas a combo kit containing only one HEPA core will leave you one filter short.

Always inspect the sealing gaskets and perimeter edges when unboxing your replacement components. High-efficiency filtration relies on mechanical perimeter pressure to force incoming air through the dense pleated fiber matrix rather than allowing it to escape around the plastic frame. When inserting new carbon pre-filters, secure them smoothly across the front face of the pleated core using the cabinet tabs to prevent fluttering noise and ensure complete pre-filtration coverage.

FAQ

How often should I change my Vornado air purifier filters?

For standard console models, the activated carbon MD1-0023 pre-filter should be replaced every three months to prevent odor saturation and trap large dust. The main MD1-0022 true HEPA filter should be replaced every twelve months. In compact units utilizing the all-in-one MD1-0039 cartridge, replace the entire cartridge according to the machine indicator light or roughly every six to twelve months depending on room air quality.

Are MD1-0022 and MD1-0039 filters interchangeable?

No, they are completely different sizes and shapes. The MD1-0022 is a large rectangular filter measuring approximately 11.8 by 10.2 inches built for AC and PCO console purifiers. The MD1-0039 is a compact square cartridge measuring 7.25 by 7.25 inches engineered strictly for CYLO50, CYLO51, and QUBE50 desktop models. They cannot fit into each other’s mounting bays.

Do I need to replace both filters at the same time on AC500 models?

Yes, large console platforms like the AC500, AC550, and PCO500 utilize dual filter chambers to move higher volumes of air. Replacing only one side creates uneven airflow resistance across the blower wheel, pulling more air through the older, loaded filter and reducing overall air cleaning efficiency. Both sides should be refreshed with matching media simultaneously.

Can I wash my Vornado HEPA or carbon filters with water?

No, neither the pleated HEPA elements nor the carbon pre-filters are waterproof. Exposing pleated true HEPA media to water damages the delicate paper and synthetic microfibers, destroying their particulate capture capabilities. Water also clogs the microscopic pore structure of activated carbon. For surface maintenance, gently vacuum the exterior pre-filter with a soft brush attachment.

What is the difference between MD1-0022 and MD1-0023?

MD1-0022 refers to the thick, white, pleated true HEPA main filter that captures microscopic particulates like dust, dander, and smoke. MD1-0023 designates the thin, black, activated carbon pre-filter wrap that attaches over the HEPA core to catch lint and absorb household odors and chemical vapors.
