Frequently Asked Questions - HR4322 PHILIPS

How does the Philips HR4322 air purifier work?

The purifier draws in air at floor level, where particle concentration is highest, and expels it towards the ceiling after filtration. It uses a three-stage system: pre-filter, Rota filter, and HEPA filters.

What is the maximum room size for this purifier?

It is recommended for a room not exceeding 30 m² (75 m³). For the HR4332 model, the maximum room size is 50 m² (120 m³).

How do I clean the filters?

The pre-filter and Rota filter must be cleaned every two months. The pre-filter can be washed with water or vacuumed. The Rota filter is washable with water or in a dishwasher. Let them air dry before reinstalling.

When should I replace the HEPA filters?

Compare the color of the underside of the filters with the replacement indicator (F). If the color matches the darkest shade, replace the filters. Generally every 6 to 12 months depending on usage.

What to do if the motor stops and the indicator light stays on?

The anti-overheating device has activated. Turn off the appliance, unplug it, wait 15 minutes, check that the filters are not clogged and that the fan turns freely. Plug it back in and restart.

Can the purifier be wall-mounted?

Yes, it can be wall-mounted (see fig. 4 of the manual). It is generally recommended to place it on the floor, with its back against the wall.

What types of particles are removed?

The purifier removes pollen, dust, bacteria, viruses, spores, allergens, and other fine particles suspended in the air.

Is the Rota filter washable?

Yes, the Rota filter is washable with water or in a dishwasher. Use clean hot water and let it dry completely before reinstalling.

Is it safe to leave the appliance on continuously?

Yes, it can operate continuously on speed 1 or 2 to maintain clean air. It is equipped with an anti-overheating safety device.

Where to buy replacement filters?

Replacement HEPA filters (part number HR 4920) are available at authorized Philips distributors and service centers.

Important

• Read the instructions carefully before you start using the appliance.
• Never immerse the appliance in water or any other liquid.
• Do not use the appliance outside or in a humid environment.
• The appliance influences the air circulation in the room in which it is used. It is recommended not to use the appliance next to an open fire.
• Always remove the plug from the wall socket before you open the appliance or before you start cleaning it.
• Do not touch any moving parts when you open the appliance. Let the Rota filter come to a halt by itself.
• Keep the cord away from hot objects.
• If the cord of this appliance is damaged, it may only be replaced by an authorised Philips service centre, since repair requires special tools and/or parts.

Clean air in your house is a prerequisite for the prevention of inhalant allergies. Your Philips air cleaner will help you remove airborne particles from the air effectively. These particles also include allergens, such as house dust, pollen and pet allergens as well as viruses, bacteria and mould spores.

When comparing air cleaners you will notice that a number of terms are used by suppliers as an indication of the effectiveness of their appliances. The standard that best reflects the effectiveness of an air cleaner is CADR (Clean Air Delivery Rate). In general, an air cleaner with a high CADR will remove particles from the air more quickly than an air cleaner with a low CADR.

Additional measures

• In urban areas: keep your windows closed during the hours in which there is a lot of traffic and when factories etc. are polluting the air.
  • Vacuum clean your house regularly. Hard floors are better than carpets.
• Use mite-proof coverings and sheets to limit the amount of house dust allergens coming out of mattresses and blankets.

How does the Philips air cleaner work?

The air cleaner sucks in air though its front and both sides. The sucked-in air is filtered by the air cleaner. After filtering, clean air is blown out from the top of the appliance. To be able to remove even the smallest particles from the air, the air cleaner has been equipped with a unique three-stage filter system.

① Prefilter

The washable prefilter catches the larger airborne particles, such as fluff, hairs, etc.

② Rota filter

This rotating filter catches particles of down to 2 microns in size (for instance pollen). When a particle enters one of the ducts of the filter, it is pressed to the wall of the duct as a result of the centrifugal force. The air is allowed to pass through the duct while the particle remains behind in the filter. The Rota filter is washable.

③HEPA filters

Finally, the HEPA filters remove all remaining particles from the air, small particles in particular. The filter is made of glass fibres which are packed so closely together that they prevent even very small particles from passing through the filter. The same type of filter is also used in most operating rooms in hospitals.

Placing the air cleaner

- As a rule, the air cleaner should be placed on the floor in a central position with its back against the wall (fig. 2-3).

• You can also hang the air cleaner on the wall (fig. 4).

- Excess cord can be stored at the back of the appliance (fig. 1).

- It is also possible to use more than one air cleaner in a room. This is advisable if the room is very big and/or has an irregular shape. In this case it is best to put both appliances against the same wall, yet as far removed from each other as possible.

- For proper cleaning of the air in a room, we advise you to use:

- one HR 4322 air cleaner for rooms with a surface area of up to 30 m² ( 75 m³ ).

- one HR 4332 air cleaner for rooms with a surface area of up to 50 m ² (120 m ³ ).

- Never cover the air inlets or outlet (fig. 5).

- When you are using a heating device: position the air cleaner in

such a way that the airflow caused by the appliance coincides with the convective airflow of the heating device. You should therefore place the air cleaner next to the radiator or other heating appliance (fig. 6-7).

• Particularly people who suffer from allergies are advised to put an air cleaner in the living room as well as in the bedroom and to let both air cleaners run continuously.

Using the air cleaner

- For a continuous supply of fresh, clean air in your room, run the appliance continuously at low (1) or normal (2) speed.

- For quick air cleaning, set the speed control (G) to the turbo setting and switch to speed 1 or 2 after approximately 30 minutes.

- Check regularly if the filters need to be cleaned and/or replaced.

Opening the air cleaner

Note that the front of the air cleaner has been provided with an automatic safety lock which makes it impossible for you to open the appliance while it is running. The automatic safety lock also ensures that you cannot switch the appliance on when the front has been removed.

• Set the speed control to O (fig. 8).
• Remove the plug from the wall socket.
• Remove the front of the appliance by pulling it towards you on one side (fig. 9).

Cleaning the prefilter and the Rota filter

- Clean the prefilter and the Rota filter at least once every two months and more often if the appliance becomes noisier and if it is used in a room in which people smoke.

Prefilter:

• Remove the prefilter (fig. 10).
• Clean the prefilter by washing it (fig. 11) or vacuum cleaning it.

Rota filter:

• Remove the Rota filter (fig. 12).
• Clean the Rota filter by washing it (fig. 13) or vacuum cleaning it. The Rota filter can also be cleaned in the dishwasher.

If you have used washing-up liquid, rinse the filters with clean water (fig. 14).

• Let the filters dry naturally (fig. 15).
• Proceed in reverse order and direction to put the filters back into the appliance.
• Press the Rota filter firmly until it snaps home.

Checking/replacing the HEPA filters

• Remove the HEPA filters from the air cleaner (fig. 16).
• Turn the HEPA filters upside down and compare the colour of their base with the colours on the HEPA filter replacement indicator (F) (fig. 17).

• Replace the HEPA filters if the colour of their base corresponds to the darkest shade of grey on the HEPA filter replacement indicator (fig. 18).
• Check the filters right away if the appliance starts to produce more noise. If the air cleaner is being used in a room in which people smoke,

it may be necessary to replace the HEPA filters more often.

- NB: new HEPA filters are available from your retailer under number HR 4920.

If the automatic cut-out is activated time and again, we advise you to take your appliance to your dealer for a technical inspection.

Automatic cut-out to prevent overheating

To prevent damage to the appliance due to overheating and to limit the risks, the automatic cut-out ensures that the motor is switched off when it becomes too hot.

To indicate that the appliance is still switched on and connected to the mains, the pilot light will continue to burn.

If this happens:

• Set the speed control to position O (= off).
• Unplug the air cleaner.
• Allow the appliance to cool down (approx. 15 minutes).
• Open the appliance. Make sure that the filters are not covered or blocked and that the airflow is not obstructed.

- Check if the Rota filter is able to rotate freely by turning it with your hand (fig. 19).

- Close the appliance. Put the plug in the wall socket and switch the appliance back on.
