Design and Build
The Hopmirth ZQA-4000C has a slim, cylindrical shape that fits easily on a nightstand or countertop. It weighs just over two pounds and measures about 11 inches tall, making it easy to move from room to room. The exterior is white plastic with a clean, minimal look. A 360-degree intake grille wraps around the base, drawing air in from all directions. Controls are on the top panel with simple buttons for power, speed, timer, and the fragrance function. An LED indicator shows the filter status. The build feels solid for its size, and the base has non-slip pads to keep it in place.
Performance and Features
Filtration System
The Hopmirth ZQA-4000C uses an H14 True HEPA filter, which is rated to capture at least 99.97% of airborne particles as small as 0.3 microns. This includes common allergens like dust, pollen, pet dander, and smoke. The manufacturer does not specify whether a pre-filter or activated carbon layer is included, but owner reviews note that the filter effectively reduces cooking odors, suggesting some carbon component. The 360-degree intake ensures air is pulled from all sides, maximizing contact with the filter media.
Coverage and Airflow
The manufacturer states the unit can cover spaces up to 1,280 square feet, but this likely assumes high air changes per hour (ACH) on the highest setting. In typical use, the Hopmirth ZQA-4000C is best suited for bedrooms, home offices, or living areas of around 200–400 square feet. Owners report noticeable improvements in air quality in medium-sized rooms. The three fan speeds allow you to adjust airflow: low for quiet night use, medium for regular operation, and high for quick purification. The unit is praised for being very quiet on the lower settings.
Controls and Extra Features
Controls are straightforward: buttons for power, fan speed, timer (options not specified by manufacturer), and a fragrance function (likely a slot for an optional fragrance pad – details not provided). A filter replacement indicator lights up red when it’s time to change the filter. There is no remote control, Wi-Fi, or app connectivity, keeping the interface simple and reliable. The unit also has a small night light with color-changing options, as mentioned in some buyer reviews.
Maintenance and Running Costs
The manufacturer does not publish the filter replacement interval or cost. Based on owner feedback, the filter lasts several months, and replacement filters are reasonably priced. The filter reminder light takes the guesswork out of maintenance. The unit itself is energy-efficient, though exact power consumption is not listed. Long-term costs will depend on how frequently you run the purifier and the price of replacement filters.
What Owners Say
The Hopmirth ZQA-4000C has earned an average rating of 4.3 stars from 374 reviews. The majority (71%) give it five stars. Owners frequently mention its quiet operation, especially at night, and effectiveness at reducing pet odors and cooking smells. Several users appreciate the compact size and easy controls. One reviewer noted a noticeable reduction in morning congestion after using it in the bedroom. Another pet owner saw a significant improvement in air freshness and liked the color-changing night light. A few users mention that the filter replacement cost is a long-term consideration, though most find it reasonable. The 360-degree intake is also highlighted as a positive feature.

Who Should Buy It (and Who Should Skip It)
Buy it if: You need a budget-friendly purifier for a bedroom, nursery, or home office. It is ideal for pet owners, allergy sufferers, and anyone who wants whisper-quiet operation. The timer and filter reminder add convenience without complexity.
Skip it if: You have a very large open-plan space and need whole-house coverage without a second unit. If you prefer smart features like app control or voice commands, look elsewhere. Also, if you want transparent specs like CADR and noise levels, this model does not provide them.
Final Verdict
The Hopmirth ZQA-4000C is a well-rounded air purifier that excels at its core job: cleaning the air in a small to medium room. Its H14 True HEPA filter captures common pollutants effectively, and the 360-degree intake ensures even circulation. The quiet operation makes it a favorite for sleep-time use, and the simple controls mean anyone can operate it without a manual. While it lacks advanced features and official performance ratings, the positive owner feedback and compact design make it a solid value.
For those seeking a straightforward, effective purification solution without breaking the bank, the Hopmirth ZQA-4000C delivers. It is particularly recommended for pet owners dealing with dander and odors, and for anyone who wants fresher air in a bedroom or office. If filter replacement costs are a concern, factor them into your budget, but the overall experience reported by users is overwhelmingly positive.
FAQs
How often do I need to replace the filter?
