Design and Features
The AC3256 Air Purifier has a very high Clean Air Delivery Rate (CADR). In fact, higher than any other on the market at 367m3/h. This means that it is capable of removing ultra-fine particles, even as tiny as 0.02 microns and can seize 99.97% of common airborne allergens.
When switched on, the air quality light indicator opens in the air well which enables users to rapidly gauge the air quality surrounding them. The colour ring is highly efficient and immediately informs users of the present state of the air in their home. For example, the bright red light means very dirty air, purple shows moderate quality of air, and the cool blue is for clean air. Since most of us live in a fairly clean environment, the cool blue light usually shows. The indicator would only get to purple and red in very heavy environments.
As well as the colour indicator, there is a professional sensor located on the side panel near the middle of the unit. This shows the indoor air quality employing a respiratory PM2.5 indicator. Should the indicator detect a high reading, you should begin to worry. In a normal environment, it registers about 10 and then falls to 1 or 2 after about an hour or two. You should note that the sensor is very sensitive and will detect dust stirred up as you walk past the unit.
PM2.5 stands for Particular Matter, and the 2.5 indicates the particles in the air which measure 2.5mm (micrometres or microns). This is a measure employed for atmospheric pollutants such as organic dust, airborne bacteria or other man-made particles such as construction dust or coal particles from a power plant but not gas pollutants.
The high CADR of the Philips 3256 air purifier means it can capture 99% of bacteria in just an hour and remove 99% of dust, pet hair, pollen and in some cases even viruses such as H1N1. It also protects against harmful gases.
5 Speed Modes are available plus 2 auto modes (auto and allergen auto).
The unit is so quiet (33dB) in auto fan mode that it can be used right beside your bed if desired.
The night mode reduces the fan speed and noise level for sleeping, and you can also switch off the panel lights and colour ring to ensure a peaceful night’s sleep.
The unit is light and easily moved around by the handle. The filters are included, but you need to unpack and replace them before use.
The unit has a 3 stage filter:
- Stage 1 – Pre-filter to filter out hair, dust and large particles, this is a carbon filter.
- Stage 2 – Activated carbon filter to remove odours and gases.
- Stage 3 – A thick NanoProtect HEPA and AC filter for extra efficient extraction and purification.
The filters are all easy to clean and replace. Just pop open the front panel which is kept in place with catches and magnets. It is simple to latch and click back into place when the filters are installed. These filters offer excellent protection to people who suffer from allergies, especially pollen which causes hay fever.
The special AL (allergen mode) is specifically to extract common airborne allergens.
By employing the air quality sensor and indoor pollution level plus airflow and operation time, the filter’s lifespan is calculated to alert the user when to change the filter(s).
The sensor touch interface has a large numerical display and intuitive options to facilitate use.
The Philips AC3256/30 3000 series air purifier is an excellent buy, and we recommend it highly. It is efficient, doesn’t take up much space and although noticeable, it is of modern design and should fit into any home with ease.
It is especially recommended for anyone with allergies but even if you don’t suffer from them, this air purifier will improve your health, and you can be sure that the air you breathe at home is pure and clean.

Health Benefits of Air Purifiers
All houses contain harmful particles, posing a threat to human health even of the residents do not suffer from allergies. From shielding your respiratory system to enhancing your mood, air purifiers are indeed necessary for those among you that seek a healthy everyday environment.
- They minimise asthma incidents, making them absolutely necessary for people suffering from asthma.
- They eliminate allergens, the substances that cause and trigger allergic reactions and shocks, including dust and pet odour. Air purifiers that do not release ozone are even better.
- They purge the air from tobacco and cigarette smoke, thus reducing the risk from developing some kind of lung disease and minimising secondary smoking. This is very important for children and elderlies, whose respiratory systems are very sensitive.
- Air purifiers extract airborne asbestos particles, reducing the risk of developing mesothelioma., True, asbestos is now used any more in building materials, but old houses may have components with this poisonous They also eliminate radon gas, that causes lung cancer.
- They also remove urban fumes and pollutants coming from outside, as well as carbon dioxide and the highly carcinogenic Volatile Organic Compounds (VOC).
- Air purifiers also get rid of mosquitoes and other similar insects, often associated with dangerous infections.
- Clean air improves mood levels, and air purifiers with ionisers are even more effective from this point of view. In addition, inhaling air free from pollutants alleviates stress.
- Air purifiers produce gentle white noise, known to improve sleep
Air Purifier Buyers Guide
What exactly is an Air Purifier?
An air purifier is a device designed to clean the air circulating in a certain room or closed environment. It uses a filtering process targeting specific harmful or potentially harmful particles, including
- pollen, plant spores and fungi;
- dust, pet dander and hair;
- mould spores, bacteria and viruses;
- tobacco, cigarette and wood smoke;
- household smells and odours;
- toxins from pesticides;
- VOCs (Volatile Organic Compounds), found in products such as paint, varnishes and cleaning supplies.
Why Should I Consider Buying an Air Purifier?
Aside from keeping the air around you as clean as possible, there are several other reasons that may necessitate the purchase of an air purifier, such as:
- minimising allergic symptoms and incidents;
- reducing asthma triggers;
- ridding the air from dust;
- eliminating mould;
- reducing pet dander and hair;
- removing or at least minimising smoke and all related odour.
What Types of Air Purifiers Are Available in the Market Today?
While there are numerous models and brands available in today’s market, they all fall into four basic categories, based on the filtration technology they use to clean the air around you.
- High-Efficiency Particulate Air Filtration (HEPA)
HEPA is currently one of the most advanced an air filtering process, using a highly dense paper filter designed to trap airborne contaminants and a strong driving mechanism.
While numerous air filters use the HEPA sign, only the ones labelled with the phrase “True HEPA Filter” are worth your consideration, since they are the only ones certified as capable of removing 99.97% of all particles of at least 0.3 microns. The rest, using signed as “HEPA-type” or “HEPA-like” can only filter particles of 2-5 microns in size, which translates in a stunning 600% efficiency decrease.
Air purifiers with HEPA filtration technology are highly efficient and are considered the best possible option for people with respiratory sensitivity and severe allergies. On the other hand, they require regular filter replacements, which, sometimes are a bit pricey. Keep also in mind that they cannot rid the air from all unpleasant smells and chemical fumes.
- Ionic Filtration
Ionic filtration emits a cloud of charged ions into the air, which in turn attach to airborne contaminants, thus adding weight to them and causing them to drop down to the floor or other intervening objects. Some models also make use of an electrostatic collection plate in order to attract fallen particles and remove them from the room.
The efficiency of ionic filtration is overwhelming; it can filter out particles as tiny as 0.01 microns! As an added advantage, they basically require zero maintenance and need no filter replacements. In addition, since they use no fan, they are much quieter.
On the other hand, the particles and pollutants remain inside the room (except in air purifiers equipped with an electrostatic plate), which means you will have to clean it thoroughly and frequently. Bear also in mind that they cannot remove odours, and they produce some ozone while operating, which is not the best thing for people suffering from asthma and other respiratory maladies.
- Carbon Filtration
Carbon filtration uses a specific type of activated carbon consisting of numerous microscopic absorbent pores, designed to trap fumes, gases and odours – not particles though. Hence, carbon filtration is ideal for refreshing the air smell, not for purifying it. That explains their low price.
- Ultra Violet (UV) Light
Last, we have air purifiers using ultraviolet light (the UV-C band in particular), which destroys pollutants instead of filtering them out. Note that the UV light is not emitted inside the room but within the air purifier. The band used is totally safe for humans but not for bacteria and viruses, since it destroys their molecular DNA structure, thus sterilising the air around you.
While capable of eliminating bacteria, viruses and germs, UV light air purifiers can only do that. They cannot remove particles. That is why UV light technology is often integrated within the air purifier with one of the other three filtering technologies.
Is There Any Other Type of Classification?
Yes, all air purifiers regardless of the filtration technology they use can also be classified in two “versions”, the Classic and the Smart Enabled ones.
- Classic Air Purifiers
Classic air purifiers basically do the job without letting you know anything about the cleaning process. You just hear their humming and see the dirty filters and realise they are actually working. Certain models are equipped with air quality sensors, but again do not share any of these data with the user.
- Smart Enabled Air Purifiers
As you have probably guessed, smart enabled air purifiers are designed to share all sorts of data through a dedicated application in your mobile device or tablet. These data may include the specific pollutants that are being removed (for example pollen, hair or dust), and notify you of the current air quality. Naturally, smart enabled air purifiers are a bit more expensive than the classic ones.
What are ACH and CADR Ratings?
These are two ratings commonly used in air purifiers specifications and is best to know what they mean before making your pick.
- ACH (Air Changes per Hour)
Usually overlooked, the ACH rating actually tells you a lot about the air purifier’s efficiency. It reveals the number of times it can clean and refresh the air in your room every hour; a 5x rating, for instance, means that this specific device can clean the air in your room five times within 60 minutes.
Of course, the rating largely depends on the maximum surface (measured in square footage or square metres) the air purifier is designed to handle. If, for example, it is designed to manage a surface of 100 square metres, and your room is smaller, then its ACH rating gets even bigger. If, on the other hand, your room is bigger, than the actual number of air changes per hour will be smaller.
- CADR (Clean Air Delivery Rate)
This rating reveals how well (not how many times) an air purifier cleans the air within a room of certain dimensions; it basically tells you about its effectiveness, and it is very useful when comparing air purifiers.
The CADR rating is measured using certain common pollutants, namely dust, tobacco smoke and pollen. Measurements usually range between 10-450 and are displayed in three consecutive numbers, for instance, 200/220/190. Naturally, the higher each number, the more effective the device is for this particular particle.
Unfortunately, not all air purifiers have a CADR rating on their specifications. Still, you should look for it anyway.
Choosing the Right Size of your Air Purifier
One of the most important specifications of an air purifier is its covered area. Make sure you check the square footage (or metre) rating of the air purifier that caught your eye and make sure whether it will meet your needs.
All models have some extra features, designed to augment efficiency and effectiveness as well as impress the consumer. The most common are:
Portability and Design Features
- Digital Controls
Digital controls can be found both in classical and smart enabled air purifiers, allowing for more precise settings.
- Adjustable Fan Speeds
This feature is by now standard to all new models, which have 2-5 different fan speeds. More advanced models designed to clean the air faster than usual, also have a turbo speed mode.
- Filter Replacement Indicators
These also tend to become a standard feature. Filter replacement indicators basically notify you that the time has come to replace all or certain filters of the device. This is very handy since it ensures the proper operation of your air purifier. Otherwise, you would consume energy but still inhale unclean air.
- Programmable Timer
This feature allows you to deactivate the air purifier at a specific time or at a pre-set time interval – usually ranging from 2 to 8 hours. Saving energy and time, programmable timers are ideal for people that need their purifier to run even when they are out of home.
- Handle & Casters
Obviously, for easier transportation. Some air purifiers with multiple filters and mechanisms can get quite heavy. Casters, on the other hand, add portability, enabling you to move the device around the room without lifting it.
This handy feature allows you to locate the air purifier more easily in a dark room.
- Remote Control
- Mobile App
A standard feature for all smart enabled air purifiers, it affords you full control of all features of your air purifier through your smartphone or tablet, along with important data about the air quality and pollutants.
Air purifiers with this feature have an extra filter designed to capture large particles, like hair or dirt and prolong the operational life of the rest of the filters, which are usually more expensive. The best thing about pre-filters is that they can be washed and reused, thus reducing maintenance cost even more.
- Antimicrobial Treatment
Antimicrobial treatment is actually a coating designed to prevent the accumulation of bacteria and microorganisms on internal filters. This feature not only improves the air quality but also prolongs the operational life of each filter.
- Air Quality Sensors
Designed to monitor the air for certain particles and pollutants, the air quality sensors constantly optimise the settings for more efficiency.
- Plasma Wave Technology
Plasma Wave Technology is an advanced ionisation method that uses water vapour instead of negative ions, making it even safer and ozone-free.
- Photocatalytic Oxidation (PCO)
This advanced filtering method is usually combined with UV Light technology. It oxidises chemicals and eliminates VOCs, bacteria, mould and fungi more effectively.
You Should Also Consider…
- Maintenance Costs
Most air purifiers require some kind of maintenance to preserve their efficiency. Before getting impressed by an array of features, you should also check the corresponding maintenance cost, especially regarding filter replacement. As mentioned, ionic air purifiers are the most economical when it comes to maintenance, but this usually makes them more expensive to purchase.
Air purifiers produce some level of noise, and if you are light sleepers or a member of the family has trouble sleeping and wakes up easily, you should make sure the noise will not be a problem.
Naturally, air purifiers with adjustable fan speeds produce louder noise while operating in their top speed or turbo mode. However, you can probably use this speed during the day, so, better check the noise produced at the lower speed.
- Energy Consumption
Most air purifiers consume around 5-200 watts, and models with Energy Star rating are preferable.
- The Offered Warranty
Last, you should also check the warranty, that is the timespan and issues it covers, thus avoiding issues with problematic components – which are always possible even with the most reputable manufacturers.
Remember, an air purifier is a device that you should be able to use for many years to come. It is nothing less than a small investment, aiming at protecting your health and the well-being of the people you love. It would be wise to devote some time to find the one that meets your needs and wishes.
