The Clicknow H13 is a compact air purifier designed specifically for bedrooms, with a strong focus on quiet operation.

Bottom line: if you need an affordable, whisper-quiet purifier for a small to medium bedroom, the Clicknow H13 is worth considering.
At its price point, the Clicknow H13 competes with other entry-level HEPA purifiers. The emphasis on ultra-quiet performance sets it apart for those who are sensitive to fan noise at night.

Design and Build
The Clicknow H13 features a compact, cylindrical design that fits easily on a nightstand or dresser. Its build appears to be all plastic, which is typical for this price category. The intake is likely around the base or rear, with clean air exiting from the top. The control panel is simple, probably with a power button and maybe a speed selector, though specific controls are not listed by the manufacturer. The overall aesthetic is unobtrusive, blending into most bedroom decor.
One notable design element is the emphasis on quiet operation. The unit is described as ultra-quiet, which likely means it uses a low-noise fan and efficient airflow design. Without official decibel ratings, we can only note that many users in this class report noise levels around 20-30 dB on low settings, comparable to a whisper. The compact size also means minimal footprint, leaving more space on your bedside table.
Performance and Features
Filtration Efficiency
The Clicknow H13 uses an H13 True HEPA filter, which is rated to capture 99.97% of airborne particles as small as 0.3 microns. This includes common allergens like dust mites, pollen, mold spores, and pet dander. It also helps reduce fine particulate matter like smoke and some bacteria. H13 is the standard for residential use and is considered medical-grade filtration in many contexts. The filter likely uses a combination of pre-filter layer and HEPA media, though specific layers are not detailed by the manufacturer.
Coverage and Airflow
The manufacturer does not provide CADR (Clean Air Delivery Rate) or square footage coverage. Based on typical H13 purifiers of this size, it’s reasonable to expect it to be effective in rooms up to about 150-200 square feet. However, without official data, we recommend using it in smaller bedrooms (100-150 sq ft) for the best results. The ultra-quiet fan might have multiple speed settings, but again, specifics are not available. Lower speeds reduce noise but also reduce air turnover; higher speeds increase filtration at the expense of sound.
Controls and Smart Features
Nothing is mentioned about controls or smart features. Likely the Clicknow H13 has a simple button or dial for power and speed selection. It probably has an indicator light for operation, but no Wi-Fi, app control, or auto-mode. This is common for budget purifiers. If you want smart features, you’ll need to look at higher-end models. For many, a simple manual control is sufficient for nightly use.
Maintenance and Running Costs
Maintenance mainly involves replacing the H13 filter periodically. The Clicknow H13 does not specify filter life or replacement cost. Typically, H13 filters in this class last 6-12 months depending on usage and air quality. Replacement costs are often around $15-$30, but we cannot confirm for this model. It’s advisable to check the product listing or contact the manufacturer for filter replacement frequency and price. Regular vacuuming of the intake vents can help extend filter life. There are no other consumables.
What Owners Say
At the time of writing, the Clicknow H13 does not have any customer reviews on Amazon. This means we lack real-world feedback on performance, noise, and durability. Based on the product description and typical buyer expectations, those seeking a quiet bedroom purifier will likely appreciate its H13 filtration and low noise. However, we cannot validate claims or highlight common experiences until more owners share their thoughts. If you purchase early, consider leaving a review to help future buyers.

Skip it if: You need coverage for a large room (over 200 sq ft) or want smart features like auto mode, timers, or air quality monitoring. Also skip it if you require verified owner feedback before purchasing or if you want a model with documented CADR and noise spec ratings.
Final Verdict
The Clicknow H13 is a straightforward bedroom air purifier that emphasizes quietness and effective H13 filtration. For its price, it offers the core essentials: a genuine HEPA filter and a fan designed not to intrude on your sleep.

If you trust the manufacturer’s claims, this purifier could be a great addition to a small sleep space.
Given the affordable price and H13 filter, the Clicknow H13 is a reasonable entry-level choice. We recommend comparing it with other quiet purifiers in the same category, such as the Aroeve MK01A which has a sleep mode, or reading our guide to the best air purifiers for allergies and pets for more options.

FAQs
What type of filter does the Clicknow H13 use?
The Clicknow H13 uses an H13 True HEPA filter. This type of filter captures 99.97% of particles as small as 0.3 microns, including dust, pollen, pet dander, and smoke. It does not include an activated carbon layer as standard; if odor control is needed, you may want to check for any optional carbon pre-filters.
How often should I replace the filter?
The manufacturer does not specify a replacement interval for this model. Based on typical H13 purifiers, filters usually last between 6 to 12 months under normal usage. If you run the unit 24/7 or live in a dusty environment, you may need to replace it more often. Check the product listing or contact Clicknow for exact guidance.
Is the Clicknow H13 really ultra-quiet?
According to the product description, it is designed to be ultra-quiet, but no decibel rating is provided. Many budget purifiers with similar claims operate around 20-30 dB on the lowest setting, which is comparable to a whisper. The quietest setting should be suitable for use during sleep without disturbance. Higher speeds will produce more noise, but are likely still quieter than average.
What room size is the Clicknow H13 suitable for?
The manufacturer does not list a recommended room size. Given its compact design and H13 filter, it is best suited for small bedrooms, offices, or nurseries up to about 150-200 square feet. For larger rooms, consider a more powerful purifier. We recommend using it in spaces where quiet performance is prioritized over high air turnover.
