Design and Build
The Wilerda 12030 filter is constructed as a rectangular, pleated HEPA filter that slides into the Clorox purifier base. It uses a three-stage filtration system: a pre-filter captures larger particles like dust and pet hair, the true HEPA layer traps fine particles down to 0.3 microns, and an activated carbon layer helps absorb odors and volatile organic compounds. The filter is made with FSC-certified paper, indicating responsible sourcing.
Installation is straightforward and tool-free: you simply turn the air purifier over, remove the filter cover, lift out the old filter, slide in the new one, and replace the cover. The compact dimensions (8.5 x 7.8 x 7.8 inches) match the original Clorox 12030 filter, ensuring a snug fit. While the filter itself is not particularly heavy or bulky, the two-pack provides a convenient supply for a year or more of use.
Performance and Features
Filtration Technology
The three-stage 360-degree filtration is the core of this filter. The pre-filter extends the life of the HEPA layer by catching larger debris, while the activated carbon layer reduces household odors from cooking, pets, or smoke. The manufacturer states that the filter captures airborne particles as small as 0.3 microns, which includes common allergens like pollen, dust mites, mold spores, and some bacteria. The MERV 13 rating confirms a high level of filtration efficiency for residential use.
Compatibility
This filter is designed exclusively for the Clorox 11030 (standard medium room) and 11031 (smart) air purifiers. It is not compatible with any other Clorox models or other brands. The manufacturer explicitly advises checking your machine model before ordering. The filter uses a slide-in mounting type that matches the original Clorox filter design, so owners can expect a perfect fit.
Replacement Indicator
The Clorox purifiers have a red filter light that illuminates after 4,380 hours of use (approximately six months) to remind you to check or replace the filter. Wilerda recommends replacing the filter every six to twelve months, depending on usage and air quality. The indicator light is a helpful feature that takes the guesswork out of maintenance.
Maintenance and Running Costs
Replacing the filter is simple and requires no tools. The two-pack means you have a spare ready when the first filter reaches its end of life. There are no additional consumables or special procedures needed. The manufacturer does not list a specific CADR or energy consumption, so we cannot comment on running costs beyond the filter itself. However, the six-to-twelve-month replacement interval is typical for this class of purifier, and the two-pack offers good value for the price.
What Owners Say
With a 4.8 out of 5-star rating from over 330 reviews, the Wilerda 12030 filter has received overwhelmingly positive feedback. Owners frequently praise the easy installation and the noticeable improvement in air quality after replacing their old filter. Many note that the filter fits perfectly and feels well-made. Some reviewers mention that the activated carbon layer effectively reduces cooking and pet odors. A few users wish the filter were compatible with more Clorox models, but that is a limitation of the design rather than a flaw. Overall, the consensus is that this is a reliable, cost-effective replacement that performs as well as the original.

Who Should Buy It (and Who Should Skip It)
This filter is an excellent choice for anyone who owns a Clorox 11030 or 11031 air purifier and wants a reliable, affordable replacement that matches the original specifications. It is ideal for those who prioritize easy maintenance and want a two-pack to avoid frequent reordering. The high owner satisfaction suggests it will meet or exceed expectations for most users.
If you own a different Clorox model or a purifier from another brand, this filter will not fit. In that case, you should look for a filter specifically designed for your machine. Also, if you need detailed performance data like CADR or energy consumption, the manufacturer does not provide those figures, so you may want to consider OEM filters if that information is important to you.
Final Verdict
The Wilerda 12030 Replacement Filter for Clorox delivers exactly what owners of the Clorox 11030 and 11031 purifiers need: a well-built, three-stage HEPA filter that is easy to install and backed by strong customer reviews. The inclusion of a pre-filter and activated carbon layer adds value over a basic HEPA-only filter, and the two-pack ensures you have a spare on hand. While it is limited to two specific models, that is by design, and the fit and performance appear to be consistent with the original.
If you are looking for a cost-effective, highly rated replacement filter that simplifies maintenance and keeps your Clorox purifier running efficiently, the Wilerda 12030 two-pack is a solid investment.
