Dreame Pet Air Purifier AP10

Range: The 2.4 GHz band offers a longer range, meaning it can cover larger areas and penetrate solid objects like walls more effectively than 5 GHz.

Speed: Generally, 2.4 GHz provides slower speeds compared to 5 GHz due to a lower maximum data rate.

Interference: More prone to interference since many other devices (like cordless phones, microwaves, and Bluetooth devices) operate on the 2.4 GHz frequency, leading to potential congestion and slower network performance.

Range: Offers a shorter range compared to 2.4 GHz and may have difficulty penetrating walls and other obstacles.

Speed: Typically provides faster speeds and higher data rates due to more available bandwidth.

Interference: Less prone to interference as fewer devices operate on this frequency, leading to a more stable connection.

Ethernet is a widely used technology for wired networking, providing a stable and high-speed connection between devices on a local area network (LAN).

Speed: Ethernet can offer higher and more consistent speeds compared to Wi-Fi. Modern Ethernet standards can support speeds from 100 Mbps (Fast Ethernet) to 10 Gbps (10 Gigabit Ethernet) and beyond.

Stability and Reliability: Because it uses a wired connection, Ethernet is less susceptible to interference from other devices and physical barriers, leading to a more stable and reliable connection.

Lower Latency: Ethernet typically offers lower latency compared to Wi-Fi, making it ideal for applications that require real-time data transfer, such as online gaming and video conferencing.

Security: A wired connection is generally more secure than a wireless one, as physical access to the network is required to intercept data.

A HEPA filter is the mechanical layer that captures fine particles such as dust, pollen, smoke, mould spores and pet dander. True HEPA filters are rated to trap 99.97% of particles at 0.3 microns, the size that is hardest to capture.

Grades follow the European EN 1822 scale: H11 captures 95%, H12 captures 99.5% and H13 captures 99.95% of particles down to 0.1 microns. H13 is the grade used by sealed medical-style purifiers.

Some manufacturers use electrostatic or "HEPA-type" media instead, which trades a little efficiency for lower airflow resistance and quieter operation.

Activated carbon adsorbs gases and odours that a HEPA filter passes straight through: cooking smells, smoke, pet odour, paint fumes and volatile organic compounds released by furniture and cleaning products.

The amount of carbon matters more than its presence. A thin carbon-coated sheet fades within weeks, while purifiers using carbon pellets measured in kilograms keep working for months.

A pre-filter catches hair, lint and large dust before they reach the HEPA layer, which is what keeps the expensive filter breathing for its full rated life.

When the pre-filter is washable you rinse it every few weeks instead of buying a replacement, which cuts running costs noticeably in homes with pets.

A UV-C lamp inside the airflow is intended to deactivate bacteria, viruses and mould spores after they are trapped by the filter.

Effectiveness depends on how long the air is exposed to the lamp, so in a fast-moving purifier the contribution is small. Poorly shielded UV-C designs can also generate ozone as a byproduct.

An ionizer releases charged particles that make airborne dust clump together so it settles or is captured more easily. Brand names include PlasmaWave, Nanoe and Vital Ion.

Ionizers are optional on most models that offer one, and consumer testing bodies recommend leaving them off because some designs emit trace ozone. Check whether the purifier lets you disable it.

How long the manufacturer expects the main filter to last before it needs replacing, usually between 6 and 12 months of continuous use.

Filter life drives the real cost of ownership: a cheap purifier with a short-lived, expensive filter costs more over three years than a pricier unit with a 12-month filter.

Clean Air Delivery Rate is the volume of filtered air the purifier produces at its highest fan speed, measured in cubic feet per minute (CFM). It is the single most useful number when comparing purifiers because it combines airflow and filtration efficiency.

AHAM publishes three separate CADR figures, for smoke, dust and pollen; the smoke rating is the strictest and the one worth comparing.

A rough rule of thumb is that the CADR should be at least two thirds of the room area in square feet to deliver a meaningful number of air changes per hour.

Recommended room size, in square feet, at about 5 air changes per hour: the AHAM standard, which works out to about 1.55 times the smoke CADR.

Brands also advertise much bigger rooms at 1 or 2 air changes per hour; those figures are not used here. Where a brand publishes no room size at this rate, it is computed from its CADR, or from its own room size rescaled to 4.8 air changes per hour.

How many manual fan settings the purifier offers, not counting automatic and sleep modes.

More speeds give finer control over the noise and airflow trade-off, which matters most in bedrooms and home offices.

Maximum noise the purifier produces at its highest fan speed, in decibels (dB). Quiet models drop to around 20 dB in sleep mode and reach the low 50s at full power, while the loudest units pass 70 dB.

Color rating by noise level:

- Green (positive): below 55 dB (quiet).

- Yellow (neutral): 55 dB to under 65 dB (moderate).

- Red (negative): 65 dB or higher (loud).

Power drawn at the highest fan speed, in watts. Purifiers are usually left running all day, so a difference of 30 W between two models is a visible difference on the electricity bill over a year.

Energy Star certified models are tested for efficiency at their standby and running speeds, not only at maximum.

PM (Particulate Matter) refers to tiny particles or droplets in the air that can be harmful to human health when inhaled. These particles vary in size, and the smaller they are, the deeper they can penetrate into our respiratory system. PM is categorized by its diameter in microns (µm), and the most commonly measured sizes are PM0.1, PM0.3, PM1, PM2.5, and PM10.

- Size: Particles with a diameter of 1 micron or smaller.

- Sources: Similar to PM0.1, PM1 particles mostly come from combustion sources like vehicle emissions, industrial processes, and smoke. They can also arise indoors from cooking, wood stoves, or tobacco smoke.

- Health Effects: PM1 particles can travel deeply into the respiratory tract and reach the alveoli, the tiny air sacs in the lungs where oxygen exchange occurs. Long-term exposure to PM1 has been associated with respiratory issues such as asthma, bronchitis, and chronic lung disease

PM (Particulate Matter) refers to tiny particles or droplets in the air that can be harmful to human health when inhaled. These particles vary in size, and the smaller they are, the deeper they can penetrate into our respiratory system. PM is categorized by its diameter in microns (µm), and the most commonly measured sizes are PM0.1, PM0.3, PM1, PM2.5, and PM10.

- Size: Particles with a diameter of 2.5 microns or smaller.

- Sources: Common sources of PM2.5 include car exhaust, power plants, industrial activities, and outdoor fires, as well as indoor sources like stoves, heaters, and candles. Urban areas with high traffic and industrial activity tend to have higher PM2.5 levels.

- Health Effects: PM2.5 is small enough to bypass the body's natural defenses (like nose hairs and mucus) and lodge deep in the lungs. Prolonged exposure to PM2.5 can lead to respiratory conditions, worsen existing asthma, and increase the risk of heart disease and stroke. It has also been linked to premature death in people with existing heart or lung diseases.

- Size: Particles with a diameter of 10 microns or smaller.

- Sources: PM10 particles are primarily generated from construction sites, road dust, pollen, mold spores, and certain agricultural activities. Natural sources like sea spray and desert dust storms can also contribute.

- Health Effects: PM10 particles are large enough to be trapped in the upper respiratory system (nose and throat). While they don't penetrate as deeply as PM2.5 or smaller particles, they can still cause irritation in the nose, throat, and lungs, particularly in people with pre-existing conditions like asthma or COPD (Chronic Obstructive Pulmonary Disease).

Volatile organic compounds (VOCs) are a large and diverse group of compounds that volatilize into the air at room temperature. Inside your home, volatile organic compounds are harmful, carcinogenic air pollutants that evaporate at normal indoor atmospheric conditions.

The majority of indoor VOCs come from everyday household staples, including sprays and aerosols such as air fresheners, cleaners and pesticides. Many products, such as glue, new furniture and carpets, construction materials and electronic devices produce VOCs through off-gassing as well. Your home will release these trapped VOCs and could harm you and your family.

TVOC (Total Volatile Organic Compounds) refers to the aggregate concentration of all VOCs in the air. Instead of measuring each individual VOC, TVOC gives you a general measure of the total level of volatile organic compounds present in a specific area.

When it reaches high levels indoors, carbon dioxide (CO2) can cause poor sleep and trouble concentrating.

Formaldehyde (HCHO) is a colourless gas released by pressed-wood furniture, laminate flooring, adhesives and new textiles through off-gassing. It irritates eyes and airways and is classified as a human carcinogen.

Only a handful of purifiers carry a dedicated solid-state formaldehyde sensor; most report formaldehyde indirectly as part of a general VOC reading, which cannot tell you which gas it is detecting.

Temperature is not just a matter of comfort, it can negatively affect sleep quality, mood, and alertness.

High humidity promotes mold growth and aggravates asthma symptoms, while too-dry air can lead to skin and throat irritation.

A screen on the purifier shows the current air quality reading, the active mode and the remaining filter life without opening the app.

It is the difference between knowing the room is at 12 ug/m3 and only knowing that a light is blue.

The display technology used, typically LED, LCD or OLED.

LED segment displays show a number and little else, while LCD and OLED panels can graph pollutant trends and show several readings at once.

A coloured light ring or bar that translates the current air quality into an at-a-glance signal, usually blue or green for clean air through amber to red for poor air.

Useful in a bedroom where a bright numeric screen would be distracting, and normally dimmed or switched off automatically in sleep mode.

AHAM Verifide is an independent certification programme that tests CADR and suggested room size in a standardised chamber, so the numbers can be compared across brands.

Manufacturers are free to publish their own coverage claims instead, and those are routinely more optimistic than the verified figures. An AHAM seal is the strongest evidence that a stated CADR is real.

Energy Star certified purifiers are around 40% more efficient than non-certified models with the same clean-air output, and are also tested for standby draw.

Because a purifier typically runs day and night, the certification is a good proxy for what the device will cost to keep on.

Ozone is a lung irritant, and purifiers that rely on ionization, UV-C or plasma technologies can emit it as a byproduct. Purely mechanical HEPA filtration emits none.

California requires every air purifier sold in the state to stay under 0.05 ppm of ozone, and a separate Zero Ozone or CARB certification confirms the device was tested against that limit.

In auto mode the purifier reads its own air quality sensor and raises or lowers the fan on its own, running quietly when the air is clean and ramping up when cooking, smoke or dust arrive.

It is the feature that makes a purifier worth leaving plugged in permanently, and it only works on models that actually carry a sensor.

Sleep or night mode drops the fan to its quietest setting and dims or switches off the display and indicator lights.

This is what decides whether a purifier is usable in a bedroom, since the quietest models fall to around 20 dB while a normal low speed still sits near 40 dB.

An onboard countdown that runs the purifier for a set number of hours and then shuts it off, without needing the app or an automation.

Handy for airing out a room after cooking or painting.

Disables the physical controls so settings cannot be changed by accident.

Worth having on floor-standing units within reach of children and pets, where a knocked button can silently switch the purifier off.

A physical remote bundled with the purifier, separate from the phone app.

Common on tower and fan-style models placed across the room, and the only way to control the device when the internet or the app service is down.

The purifier swings its air outlet from side to side to spread filtered air across the room instead of projecting it in one direction.

Found mainly on bladeless tower models, where the oscillation angle ranges from 45 degrees to a full 350 degrees.

The purifier doubles as a cooling fan, projecting a directed stream of filtered air at you rather than just circulating it around the room.

Combination units save floor space and a plug, but cost noticeably more than a purifier of equivalent CADR.

A built-in heating element lets the same unit warm the room in winter while it keeps purifying.

Heating draws well over a kilowatt, so a combined unit behaves like a space heater on the electricity bill and should be compared against one.

A water tank and evaporation system that raises indoor humidity alongside the filtration, aimed at dry heated rooms in winter.

The trade-off is maintenance: tanks need refilling and regular cleaning, and a neglected one becomes a source of the very contamination the purifier is removing.

The ability to create automated actions based on sensor readings or schedules.

Automations can trigger other smart devices, send notifications, or adjust settings without manual intervention.

The ability to track and store historical data over time.

Historical records help you identify patterns, track trends, and review past events for security or optimization purposes.

It keeps working, and can be controlled from inside your own network, when the internet is down: over Zigbee, Z-Wave or Thread through a local hub, a native Matter or HomeKit connection, a documented local API or an official local integration.

A product without local control stops answering during an internet outage and depends on the maker's servers staying online.
